[Marvel, 616] What specifically makes a being a god?

There would seem to be physical factors that distinguished Gods from other beings, In *Thor: God of Thunder* there was a time machine that could only be powered by Godblood, as well as a  magic weapon that was designed specifically to fight Gods, and did very well despite being used against many different Gods from many different planets.

On Earth we can trace Gods back to Earth's Elder Gods (mainly Gaea, but there are a few descendants of Set and Chthon), but what about Gods from other plants? We've seen Gods from the Skrull homeworld, Zenn-La, and a myriad of planets in *Thor: God of Thunder*. 

What exactly defines someone as a god? What physical or supernatural features are associated specifically with Gods? what differentiates a God from a demon?

As we have seen, cultures from all over the universe have had Gods of some sort. Dieties, like music and language, seem somewhat universal in that sense.

If we wish to speculate about their origins, we may look at what is common among all Gods: worship. It seems most likely that Gods are a form of living story, animated by the collective worship and adoration of their followers. Now, this does bring us to something of a "chicken and egg" paradox: which came first, the worship or the God?

Based on the fact that each culture has Gods with contradictory histories, it seems that Gods really must be the product of worship and not the other way around. Mortals invented stories to explain the world they did not understand, and in their explanation, they evoked the most powerful and subtle magic of creation. Mortal beings literally wish Gods into existence, and as such the God has properties that are as grand as a culture can muster with its collective worship.

Gods, then, are more metaphor than matter. They are a story echoed by the universe after it heard the first voice of the first mortal.
