There is a theory that it did, and here is some evidence to support that.....

If the conditions are right, why should life not evolve anywhere?

Well, there's no reason at all why life shouldn't start anywhere.........if the conditions are right. And it's the last part which is the point. What created those conditions on Earth? Did it just happen, or did the final, or vital, ingredients land here?

What do you think?

Earth is a product of collisions of solar system objects, so therefore the answer is yes.

I think life could be (and almost certainly does) exists in forms that we do not recognise. Physically or statistically demonstrating it in a way that can easily be understood, is as yet, beyond the power of any (?) humans.
At last, astronomers seem to be looking and finding places where there may be earth-like planets.

I think life just happens by chance.

In an infinite cosmos I fail to understand, that no matter how rare life may be, there can not be
infinite varieties of it, in an infinite number of places.
This idea is based upon the assumption that the cosmos is infinite and is expanding. (Sorry about the double negative).

What puzzles me, not having much of a clue about atomic physics, is where matter itself came from.

Big bang. Ok.

If there was nothing before the big bang where did the energy to drive it come from?


I think too much.

Help! I have wandered into this thread by mistake! Can someone help me find the way out?

Inina,

Bad luck. There are an infinite number of ways out. Which way would you like to go?

Don't worry about it, nifty, we all think too much over here. At the moment of the big bang and before, we get into philosophical arguments and "theories" that don't have evidence to support them. After that moment, we have quite a lot, but we still don't know very much.

I'd go back to the Big Bang thread if you want to continue that line of thinking. This one is about life, which is rather a long time after the big bang.

In my view, the 1st article is right. And the good dr has said it quite directly.

With a Big Bang?

Better than with a whimper.
