As per the last decade of cosmological research, the universe will not collapse. Its expansion is accelerating. According to most of the experts in this field, the universe will expand and expand until stars can no longer form as all the hydrogen has been used up and the whole place will essentially Burn Out "as the temperature everywhere asymptotically aproaches absolute Zero"
Neil deGrasse Tyson, Director of the Hayden Planetarium in NYC. He is a leading expert in the field.
However, they also theorize that there may be ways of escaping this fate for any beings still alive may be able to open a wormhole to a young universe and seed it with Infromation, in the quantum sense of the word. Since Einstein-Rosen bridges (the proper name for wormhole) are believed to be highly unstable, you may only be able to get objects at the molecular or atomic level to pass without destabilizing and closing it. But the important thing is that would be enough to transmit the quantum information for the next steps.
This incomprehensibly advanced civilization could send enough information through the wormhole to create a “nanobot,” a self-replicating atomic-sized machine, It would be able to travel at near the speed of light because it would be only the size of a molecule. It would land on a barren moon, and then use the raw materials to create a chemical factory which could create millions of copies of itself.
A horde of these robots would then travel to other moons/planets bearby and create new chemical factories. This whole process would be repeated over and over again, making millions upon millions of copies of the original robot. Eventually there would be Quintillions upon Quintillions of them, rearranging matter, perhaps just asteroids into bodies that can support life (i.e Earth)
Next, (as The DNA sequences of the probes’ creators would have been carefully recorded) the robots would have been designed use this genetic information to then clone the species after recreating a suitable environment, enabling the entire race to be reincarnated. There may be limitations to this process that result in the inability to send enough information to recreate this master race in all its former glory, but they would survive and begin anew.

And God said, Let the earth bring forth living creatures
after their kind, cattle, and creeping things, and beasts of the earth
after their kind: and it was so. And God made the beasts of the earth
after their kind, and the cattle
after their kind, and everything that creepeth upon the ground
after its kind: and God saw that it was good.

And God said, Let US make man in OUR image, after OUR likeness.....
And God created man in his own image, in the image of God created he him; male and female created he them. Genesis 1:24-27
Sure its mostly the speculation of Quantum Physicists, and a little from myself, but the point is:
RuhlFreak55, your "Extraterrestrial Gods" hypothesis is -according to the known laws of physics- fundamentally POSSIBLE
