>>521932I'm more honestly pointing out that you probably don't know much at all about either the Big Bang theory or how scientific theories are formulated based on everything you've said.
For starters, cosmologists do not claim to know where the Universe came from nor why nor whether it has a beginning. The Big Bang is not stated to be the beginning of the Universe within the confines of the theory, there is no theory of how the Universe came to exist, scientists openly admit that they do not know whether there was a "before" the Universe
When you say scientists do you mean Reddit atheists? Because those people are not scientists. The Big Bang is not even something that actually ended either, what scientists state, based off observable evidence, the Universe began expanding about 13 billion years ago from about a single point, expansion is an observable phenomenon as galaxies are observed to be uniformly moving away from each other, with the furthest away galaxies also being the oldest galaxies, which can be calculated according to the distance light takes to reach the Earth from far distances, the fact of expansion from a single point is observable through the uniformity of the universe.
These aren't things scientists just decided at random because they couldn't seriously test their ideas and observations like a Bronze Age tribe located in modern Palestine did.
