Your DNA example doesn't work because, first it's a natural occurrence and was mentioned only after being observed and properly documented unlike the god created during campfire tales of desert nomads who sacrificed goats while chanting about their deity.
If you weren't so fat, ugly and stupid you could tell the difference between the two.
Again the concept of DNA was presented after observable and testable data was produced. The concept of god was presented during animal sacrifices by desert nomads who thought the earth was flat and created during the Bronze Age.
Green leafy vegetables Buck, go buy and eat some.
Wrong again, GiveMeLiverwurst.
Many things have existed for long periods of time while nobody could show observable evidence of it. Ever heard of the DNA double-helix? Did it begin to exist at the same time as the microscope?
FYI, I am not fat. I weigh 325 and have a lower body fat percentage than you, most likely. And I doubt YOU can bench 500 lb., either.
