If man has been there millions of years ago, how come we  only invented most of the things just 150 years ago?

its not that these people werent thinking of science it was just that much of the "masses"(peasents) weren't educated. the ones that were were from the clergy(church) so a science was not part of religion as we all know because God invented it all and there shouldnt be any questions or impovements but there were scientists who had ideas like devincci he had sketches of some good working tech that we have now.

nope you cant prove it either way.\n\ni was watching a show on evolution yesterday though and i had an interesting thought.\n\nyou remember hearing that if earths history was an encylopedia that the history of man would only be on like that last half of the last paragraph of the last book?\n\nwell then why didnt intelligent life evolve during that whole time? \n\njust a thought.

From archaeological evidence it would appear that the first groups of people to stop being hunter-gatherers and set up permanent settlements with agriculture and domestic animals and a structured community was in Sumer. They also started us on the road to mathematics, geometry, poetry, fancy religious rituals, reading, writing and astrology. They seemed to have been pretty fair at homeopathic medicine and they were positively wizard at law. Politicking seems to have been another of their inventions, discoveries, whatever. They're the first we've ever found to record elections of local officials. Imagine that. And you thought the USA invented democracy. Or maybe the Athenian Greeks. Sorry, Sumer beat 'em both by about 3,000 years!\n\nLocation: Modern-day Basra area, in southern Iraq.

Modern man is not the same as ancient man. We are weaker, sicker, and stupider. Our DNA continues to amass errors. Our technology continues to oustrip our morality. Our connection with God continues to fade.\n\nThe thing we really seem to have most in common with ancient man is our pride.

They wouldn't have changed at all over the past 500 years.\n\nReal progress only happens by merging different ideas.

This site has a timeline of everyday inventions; it covers more than the fifty years you want, but it is fairly short and there seems to be some other useful information on the site.\n\nhttp://www.factmonster.com/ipka/A0768871.html

When Plato's ancestor Solon went to Sais in Egypt (600 BC), the priests told him about Atlantis. They also said that inscriptions on their temple walls told how many times civilisations had risen to great heights and then fallen because of natural catastrophes such as floods, fire, earthquakes, etc. I think that maybe we are being a little presumptuous to think that it can't happen to us. I have spent the last 15/20 years researching a related subject and in my opinion the last great catastrophe was 9600 BC, with the sudden and abrupt end of the mini-ice-age called the Younger Dryas period. I believe that this is the basis of the Biblical flood. Getting back to today - the Christian versus Muslim thing - yep, of course it coming, you can smell it! I should imagine that most of the faceless men in grey suits already know this and are moving their pieces on the world chess board accordingly. Humans are amazing - we've been on the moon and sent machines out to beyond the solar system, I can pick up my phone and talk immediately to a person on the other side of the world, I can sit in my armchair and with the smallest of thumb movements be entertained by 100 different TV channels - but with the flick of an eyelid this civilisation can be destroyed because people believe that their unseen and unproven overlord of the cosmos is better than the other man's invisible and all-seeing ever-present boss. It almost makes you want to scream! We're such clever animals - but I don't think that we're too intelligent - and when it's all over we'll begin again.

There are many things that are happening since the last 5000 years. there are some societies who think good when they develop and some find it comfortable in th eold surroundings. What matters in the quality of what happen around us rather than the time since when it is happening.

This is a very good question. Also I can tell for a change it is not a homeworkk question (thank you).\n\nIt's weird ,isn't it? Humanity in less than 10,000 years from our first civilization until now, monkies in that time have done nothing. Makes you wonder, doesn't it? The only thing I can think of is our larger brains. So will any animal ever reach our level of advancement? I doubt it. Some animals do communicate with each other. Some animals have hands like you said so they could build houses with those hands and tools, but they don't. Maybe humanity is the like the Chosen Ones, and can do so much more than animals.

Humanity, pre-history.

Based on fossil, genetic, and molecular evidence, we have a long train of ancestors in our history.  Modern humans and other primates, such as monkeys, have a common ancestor that lived about 25 million years ago, and our ancestor would probably *not* be considered a "monkey."  Before that were early mammals, and before that mammal-like reptiles, the sauropsids. Before that were early reptiles, and amphibians.  And yes, before that, about 440 million years ago, one of our ancestors was a fish.  So you are correct.

I have studied this topic for nearly 4 years. I believe it is less than 7,000 years. I had trouble with this until I saw how things are dated. Then I knew that there was no "proof" of anything over  about 5500 years old. Every thing over that age, whether 20,000 years or 4.5 billion years is speculation. I have worked in the science industry for about 30 years. I know my way around a lab. I certainly don't know everything, but I know these old dates given to fossils and rocks are speculation. Recent discoveries in DNA and Micro-biology have placed serious doubt in a lot of scientist minds about evolution. I know for a fact that creation is debated by scientists daily. Many can no longer support theories once held by the majority.

Not necessarily.  We do all those things because protohumans were exposed to evolutionary and selective pressures that lead to creative humans capable of technological advancement.\n\nIf, and that's a big IF, any of those animals you mentioned which that are rather intelligent get exposed to these same selective pressures over a LONG period of time (it took us 2 million years to figure out fire, so it'll be a while), then sure why not.  But the odds of that happening are very small, but you never know, we'll see in 5 million years what happened...\n\nCheers.

the problem is that history can not be proven. science deals with the now. right now we have fossils and bones. what does this mean? that somthing lived and died not that they evolved over millions of years. if the biologists knew anything about astronomy they would realize that the earth is slowing down (hence the leap second) and if somthing is slowing down that means it used to be going faster. and if you do the math on this billions of years ago the earth was going so fast that day and night were one and nothing could stand on its surface.\n\nlets think for ourselves and not let the government or our textbooks tell us what to beleive \ngalleleo along with almost every other inventor would have never made there discoverys had it not been for there mistrust of textbooks.

Considering that we are of the same stuff that all other life on Earth is made of, it seems very unlikely.  Of course that does not eliminate the possibility that life on Earth was seeded from some outside source 2 billion years ago.

The latter seems much more plausible. Man has made a lot or gods.
