I think genetics proves evolution. Humans are genetically related to all other life forms. Like Darwin argued against the intellectuals of his time, why would God in all his glory and infinite qualities would make his creation from such a small reserve of elements?
And now we know that hydrogen is the source of everything in universe. Nuclear reaction of hydrogen eventually created everything from stars in distant galaxies to gold under the rocks to my nails.
Perhaps God created hydrogen.
"I think genetics proves evolution." You had me at "I". /sarc
The reason that I see that there are genetic similarities is that we are carbon based life forms living in a nitrogen/oxygen environment. Of course there has to be similarities. Almost all creatures have similar structures and the genetic blueprint for those structures would need to be similar. Since humans closely resemble monkeys/apes physically, you would expect there to be genetic material that matches. It doesn't "prove" evolution or common descent, it just proves that certain genetic sequences work well to produce certain physical charateristics. If a certain sequence produces color of hair/fur, I'd expect to find that sequence in any animal that has the same coloring.
So, if you have ID then it would make sense that the designer would use the same sequence in every creature because it works so well.
