Xeno, You stated that:
"Scientists on the other hand, with the Big Bang, think that time also began with the Big Bang, that is, nothing came before the Big Bang because that is a meaningless question to ask. It just happened. Nothing made the universe, it just happened. There are other conceptions, such as multiverses, etc., which I am not going to wade into." There are actually some scientists who are trying to prove that they know what happened before the Big Bang. There's a research group called the Perimeter Institute in Canada which is proposing the Brane Theory. This is alternately called the "Big Bump". Essentially, the theory states that the universe began due to the collision of two membranes in the 11th dimension. However, most of the scientific circles have not accepted this idea to be plausible. Also, your statement that the universe just happened raises some questions for logical and scientific reasons. As stated in the Kalam Cosmological Argument, your statement cannot stand further logical scrutiny. Basically, the KCA states that the Prime Mover is the cause of the universe. In science, Roger Penrose, the professor-emiritus from Oxford University, believes that the universe is a product of endless explosions that occur after eons of time. However, he has not been able to produce a scientific paper to prove that this idea is true.
