The ancients knew a lot more than we give them credit. Heck, if a Greek could stick a stick in the ground, measure its shadow and tell you the circumference of the earth, my hat's off to 'em.
Is your argument that because someone used repeatable and provable science and math to move knowledge forward that his cultures unprovable myths might also be true? Because I saw a dog and can prove it, UFO abductions might also be real?
As usual, religion gets it exactly backwards.
