I think merely the potential for higher intelligence proves that higher intelligence exists. The idea that we are moving forward in time is merely an illusion. Therefore at some point in time the highest possible intelligence already exists. What possibilities exist with regard how far intelligence can evolve? Given infinite time the answer is mind blowing. If we were not created by a God at the very least there is someone somewhere in time smart enough to qualify for the job. This "super genius" would no doubt figure out immortality, time travel, miracles, walking on water, etc.
