For me, Metis, it is not just that evidence is lacking, but that a bit of careful thinking tends to strongly suggest that our universe was not intentionally created. Here, for me, is the key to that argument: we must posit a being of pure spirit, with neither physical, spatial or temporal qualities as part of its nature, that suddenly notices, "Do you know what? We don't have and stuff or any time, and that needs to be corrected!"
Add to that the certainty that "stuff" and "time," when taken together, inevitably leads to change -- and thus decay and death --which until that moment never existed!
It would take a pretty monumental argument (the like of which I have not heard yet) to convince me of that.
