Question: How do you think life began?

…on Earth ? Hmm,…that is a difficult one.

Life needs some sort of molecules that can replicate, or copy, themselves. I guess those were either produced by the conditions on Earth at the time
or came from “somewhere else”.

Once an initial simple mechanism of copy was in place, this could then slowly develop into something more complex and more dependent on the previous generation…still a long way to real “life”, but a possible scenario ?!
