My "God R Us" theory is supported by both science and religion, though only in fragmentary ways because both remain so primitive.
Please accept my airy dismissal of your objections in advance.
We (home sapiens deus) are destined to evolve into God(s)--we have done it before, explaining (1) why Adam and Eve were created in "Our" image, (2) why we pre-Gods should avoid provoking jealousy by worshipping no other Gods (i.e., the last cycle's losers, Republicans), (3) why the Kingdom of Heaven is "within" us, and (4)why the universe seems precisely tuned for our emergence and survival.
Furthermore, there is no logical limit to evolution:
mutation + selection + a-very-long-time-indeed = God R Us.
Many religions describe a Creator God who in some future time will return. In reality, this refers both to our former status as our own Creator as well as the future in which we have again fully evolved our God-Nature.
In the face of the Big Rip, Big Crunch, or Big Freeze, etc. (hey, We can change it each time, who's to know?), We, at long last fully Gods again, will look around and say, "Whoa! Nice ride! Over already!?" [Note that the evangelicals are the back-seat kids constantly asking, "Are We there yet? Are We there yet?" They will be selected out somewhere in the demigod state for the Unforgivable Sin of Tedium...]
Out of boredom, We will gloriously expend Our God energies in one Organismasmic burst to again birth the universe (yes, God is Omnisexual): note the primitive religions where the "God" is slain to engender new growth and harvests--like the afterglow of Creation, this is a faint echo of the truth. Again, our primitive religious texts have it a bit wrong--
God (in the evolved phase) gets the Rapture, we (in the evolving phase) get the genes.
Then We roll out the Whole Enchilada again just for fun.
