Creationists have an advantage, too. They can claim divine intervention for any and every kind of inexplicable phenomenon. This may not sit well with those who depend upon senses and experience alone as a determinent of truth, but it does not have to.
The fact that scientists of both stripes conclude the universe entails substances dating in the billions of years bears not the slightest impediment toward what the Bible teaches in all its simplicity, considering they attest to a Creator with no beginning or end. A curved universe (as scientist are beginning to learn exists!) is fine testimony to a single creator eternal in nature, for a circle has no beginning or end.
But I'm with you entirely in viewing as rather comical the scurrying and obfuscation evidenced by these die hard atheist/evolutionist types. Nonsensical, really. Oh well. It is unbecoming of us to relish in their self-delusions. Such are we ourselves by nature, right?
