I understand (I think) about the idea there is no "goal" to evolution. Except perhaps to survive? But again, a non-thinking principle like evolution obviously cannot have a goal. Although chickens lay eggs. That might be their goal, is it evolution, because evolution doesn't have a mind, or goal in mind, does it? Of course not. I have a feeling that I might hear about how chickens came about -- by evolution, of course. They do look like dinosaurs a little, maybe they are said to have evolved from dinosaurs? P.S. I don't KNOW how chickens came about --
Just saying...about the theory. I do mention gravity as an essential principle of existence as we know it. More I think about, the less I really understand about gravity except that it's a very powerful force. You may think/believe that gravity came about by -- physical (physics) means perhaps? I am not interested in Einstein's philosophical idea if I read right that he wanted to know HOW God DID IT...I do not believe like Einstein did (he isn't thinking now), even if I don't understand his theories right now. I believe there is a God who cares...and is the Giver of life in its ultimate passage. That means again that He does not form abnormalities, or defects, but allows it right now as a result of genetics.
You may make excuses for those 'believers' who belong to a church or religion but who also believe in the validity of the theory of evolution -- obviously you do not share that idea with them about any type of god these persons may think may exist, so I won't say any more about this. I'll try to remember that. If you want to question them, please do.
