There are different schools of thought on that and I've seen real scientists tell you that you DON'T understand science.
Metmom, surely you know that when FreeDumb refers to “real scientists”, he’s not defining them by real, actual science! What he really means is that he agrees with the scientists who worship at the alter of the Temple of Darwin, and he disagrees with the scientists who worship the God who created the heavens and the earth in six days. Actually, he goes much further than that. FreeDumb adtually agrees with the Evo-atheists when they say that life looks like it was designed for a purpose, but that in reality it is all just an illusion randomly generated and then preserved by darwood’s natural selection god.
Thanks for the ping, mom. Enjoy your Memorial Weekend.
