I'd want to witness the arrival of the first human life on earth. With all the theories of evolution, creation and so on, it would be nice know, once and for all, just how the hell we got here.

Earth is a school.  We are electro magnetic beings travelling around in flesh and blood.  Our purpose here is to evolve into a higher state of existance.  This means that we are to refine ourselves here into purer beings.  That means peaceful, loving, patient, kind, gentle, joyous, faithful, good people who know how to exercise self control. It is my understanding that when we die - we first come face to face with all of our deeds - good or ill - and experience how we affected other people in our lives - then at some point we go to the place where there are other souls who are at the same level of being as we are. \nSo don't act like hell if you don't want to go there - and become the person you want the rest of the world to be. \nRead up on Christ and Buddha - they are living examples of the right way to be to get past the hell states.l

Of course I would! Who wouldn't? Maybe people who are afraid of the future. I would want to know what happens to me and Earth. And maybe I could prevent mistakes from the future info. Looking into the future would be great.

Because of the curvature of the earth.

Because humans are curious by nature.

Yes. Because:\n1. Interstellar comets contain organic matter.\n2. It is statistically very unlikely that Earth is the only place where live can occur, because within one galaxy there are billions of stars in the "green zone" (the zone where life can exist) and many (if not most) of these would have terrestrial planets. Multiply that by billions of galaxies and the chances that Earth is unique are staggering.\n\nHere are two reasons I would not accept:\n1. "Intelligent life has visited Earth." People have great imaginations but most people are also nutcases. Nobody has definitely proven any encounters such that they would be taken as scientific fact.\n2. "Life on Earth started on another planet." Even though it is possible, it is speculatory.

we will never know whats going on out there if we dont explore it.\nmaybe there is aliens out there who would want to communicate with us or there may be some asteroid out there that is going to hit the Earth in near future.

You would need to provide vast amounts of resources provided to earth from space and travel into space. People fight and hate for the limited resources  and wealth available.

Because living forever would get boring! And there would be too many people on earth! Not enough space!

Why would anyone want to do that?  Are you a naturalist or something?

The Earth is in danger of becoming almost totally inhospitable for most higher life forms.  Unless we start being more intelligent and get population and resource management under control, the Earth will do if for us.

An alien, literally, is someone who travels (and possibly lives) in a region or country he/she/it does not really belong in (due to polits, culture, etc).  So, I believe in aliens from other countries ... there are enough of them all over North America :P\n\nBut then aliens from other planets is a little too much to digest. \n\nWell, then again ... it's hard to believe that with the size of the universe, we're the only form of life in the ENTIRE place.  So, there is other life, or at least I'd like to think so.  \n\nBut it's scary to think that this other life has actually travelled God knows how many light years to get to our planet.  The only form of life that there is in our galaxy that we know of is the bacteria that is found on Mars.  So whoever these beings are, they'd have to travel from some other galaxy out there somewhere ... And if they actually did, it shows that they have way more technology than we do.  \n\nSo I'm better off believing that there are no aliens ... in the sense that we have yet to receive visitors from outer space.

Earth is great, but some of us are very curious about what lies out there.

The laws of probability makes it a yes to your question.  We are not alone.  In fact earth is just a speck in our own galaxy.  Our galaxy is just one of many galaxies.  Yes it would be amazing to find other beings....provided they were friendly...LOL

Why on earth would you want to do that?
