how did the first living thing come to be?

God breathed life into it and viola!  A LIVING THING!!!

The egg.  Dinosaurs were laying eggs far before chickens had evolved, so the egg had to've come first.  :)

Evolutionary theory seems to point toward the egg being first. All animals on earth mutated and evolved from the first life forms. It's likely that the first chicken as we know it today hatched after eons of genetic mutations and changes.

The first organisms to live on the earth belonged to the kingdom archaebacteria.

Either answer would be wrong.  The universe came first.

The earth came into existence by some as yet undetermined process, the most likely of which was a "big bang" whereby all existing planets and solar systems began to form into their current transitory states. During that process, animal life began to form on the earth, by yet another unknown process. The earth is currently in a state of transition that will eventually result in its return to the previous unknown condition that resulted in the "big bang."\n\n\n\nNow send me $5 or I'll put a curse on you.

recent studies have shown that chicken came first as life started with single cell organisms, & by adaptation they grew to multi cellular which were mammals . so the chicken was formed before egg.

Several billion years ago, the first simple amino acids formed crude proteins and RNA to act as simple genetic coding. Over time, these nondescript organisms evolved into bacteria, then photosynthesizing bacteria. Eventually they evolved into simple invertebrates capable of sexual reproduction, and through tweaking of the ovulatory cycle, were able to lay fertilized eggs outside of their body. These invertebrates became fish, then amphibians, then reptiles, then birds. From those birds evolved the ancestor of the chicken which after 4 billion years of evolution was already capable of laying eggs.\n\nThe end.

Yes, this is assumed to be the case, and much has been written on it, but little is known in detail. The first life form, or the ancestor of life, depending on how you define things, is generally presumed to have been a single molecule or small group of molecules capable of doing two things: 1 Catalyze reactions in its environment that lead to a copy of itself being assembled and 2 be nontrivial enough in structure so that slight changes can result in mutations still capable of performing number 1. 1 has been achieved in highly specialized environments, but not 2. To be a candidate for the first natural life, 1 would have to be possible in the natural environment of the time. Until such is found, there will remain a gap in our understanding that some will prefer to explain by the action of their God of the Gaps.\n\nI've listed one book that discusses such speculations.

The fruit came first.\n\nRead up!

Science estimates that the first DNA forms of life were present on Earth around 3.5 billion years ago.

Scientifically speaking, the egg must have come first because there was a non-chicken animal that evolved into a chicken, and the only way for that non-chicken animal to have evolved into a chicken is if there was a mutation during meiosis (reproduction). So the non-chicken animal would have laid an egg which became a chicken.

the first multicellular being was Dictyostelium from symbiotic realtionship

Well, that's very interesting cuz if u think about it, if it's NOT alive but creates life (plants) than how could something dead create life???  How long could earth possibly live/survive without that glorious light?  Is the earth alive? Hmmmmmmmmmmm\n\nVery thought provoking, I'll have to put this question on my watch list!  It is an eternal source of power tho (like God).  So my answer must be yes than:o]

The planet earth is at least 4500 million years old. The earliest signs of life date back 3000 million years, and by 600 million years ago quite complex animals and plants existed. \nThe story of the backboned (vertebrate) animals - the fishes and other forms that eventually led to humans -began about 600 to 500 million years ago. The first definite fossil of a creature with a stiffening notochord along its back was a Cambrian animal called Pikaea, which was discovered in 560- million-year-old rocks in Canada. The oldest complete fish fossil so far found came from central Australia, and was a jawless, armoured fish called Arandaspis, which dates from the early Ordovician period. This small filter-feeding or mud- grubbing fish lived in shallow coastal waters over 480 million years ago.

Life begins when we realise the purpose behind our existence. Life is not just taking birth, thats just the existence. \n\nExistence + Wisdom = Life\n\nA scientist may answer to this question in a very different manner and a philosopher may answer something else.

if you belive a superior being created all life as it is than the chicken came first\nif you belive in evolution the egg came first(because the ancient reptile would have laid an egg which would then become a bird.)
