Intelligence- that's a different matter. Are there intelligent life forms out there? You've got me. BUT, you can't tell me that somewhere, on some planet out in the middle of nowhere, there isn't some "stuff on a rock." An ocean planet with a rock sticking out of the waves, with crud on it. Gloopy self-replicating crud. ha
Ah, but life is about competition, even among single species.
Competition will eventually bring about specialization and specialization will bring about instinct.
Instinct will eventually bring you to the top of the food chain and from there tool development.
Tool development will bring about modification of your environment to a point where basic survival is no longer a concern leading to social competition.
Social competition will lead "eventually" to intelligence.
Ok now everybody, that was a high school (maybe a little more) evolutionary progress sheet. I know it might be wrong in it's development, but it is essentially what is proposed by evolutionists.
My former post was not suppose to be about evolution, but it does concern it strictly scientifically speaking. I DO NOT WANT TO ARGUE EVOLUTION VS. CREATIONISM
