no, its only the most accepted theory. there is a major difference.

once a extreamly long time ago (i want to say 5 to 6 thousand years) it was believe that the world was flat. this theory was accepted as a proven fact then. eventually it was disproven.

once it was accepted as a proven fact that the earth was round, but that it was the center of the universe. this was eventually disproven too.

once it was accepted as a proven fact by the vast majority of scientist that man could not fly and never would. this has been conceided by most as not proven now.

there is no way of testing it, and it does explain things now known. that does not mean it is a proven fact. until it is proven it is not a proven fact.

the more man learns, the more he realises, he really does not know anything.
