Democritus's Steady State Vs. Plato's Big Bang

There is not much new in cosmology as far as I can tell.

"... so far as time is concerned we see that all with one exception are in agreement in saying that it is uncreated: in fact, it is just this that enables Democritus to show that all things cannot have had a becoming: for time, he says, is uncreated. Plato alone asserts the creation of time, saying that it had a becoming together with the universe, the universe according to him having had a becoming." -- Aristotle, Physics, Book VIII, 350 B.C.

Plato's response is customary for Big Bangers:

"And Aristoxenus, in his Historic Commentaries, says that Plato wished to burn all the writings of Democritus that he was able to collect; but that Amyclas and Cleinias, the Pythagoreans, prevented him, as it would do no good; for that copies of his books were already in many hands. And it is plain that that was the case; for Plato, who mentions nearly all the ancient philosophers, nowhere speaks of Democritus; not even in those passages where he has occasion to contradict his theories, evidently, because he said that if he did, he would be showing his disagreement with the best of all philosophers...." -- Diogenes Laertius, historian, 3rd century
