Good question. Because He answers prayer and because it is obvious that He created (Romans 1:19-20).
Yes, He answers prayers with yes, if the reqest comes true and with no, if that does not fit with His will. Same hit ratio as praying to that glass of beer in front of me, I am afraid.
And just because Paul says that something is obvious, does not make it so. I mean, who would create the black plaugue bacterium?
