I ask again...what did the first life live off of?

Animals don't eat rocks!

So when life first began...it required other life at the same time....and that life required life...

So did a whole ECOSYSTEM evolve all at once?

Unlikely

Please reply without insult.

Nice try. Circular reasoning. See: reasoning, circular.

You ask, what did first life live off of? Don't know. Evidence suggests that early (not necessarily the first) life did live and reproduce and evolve. We're here, aren't we? Whether I know how it happened or not is not relevant.

You say, animals don't eat rocks. When did animals first emerge? Plants essentially eat rocks, so could the first life have resembled plants more than animals?

"life did live and reproduce and evolve. We're here, aren't we? Whether I know how it happened or not is not relevant."

Your argument against circular reasoning is hollow....

We evolved because we are here...and we are here because we evolved?

If science hasn't taught you how it happened...maybe science needs help Designing an Intelligent explanation
