it's classified as fact by the scientific community
No.
A fact is very specific.
For instance, it is not a fact that when you let go of a ball in the air, it would drop to the ground as this cannot be guaranteed. The ball could very well fly up into the sky based on the density of the ball, or if it was magnetic and over a magnet, or any number of things. However, it is a fact that in general: objects with mass will attract each other.
The big bang theory is a very likely theory, however without any sort of time machine and ability to document it's occurrence, it is just as likely that the world was created by the slaying of a frost giant and his body was stretched out to form land, and his blood to form the oceans. (points if you get the reference to mythology)
