In our experience of the universe, everything came from something else. That’s why the fundamental question of creation is not what created life, or even what created the universe. It is, “Where did the matter and energy that went into the universe come from?”
The big bang theory does not answer this question. It says that before the big bang, all of the matter in the universe was compressed into a singularity (maybe.) Regardless of what cosmology you select, all are defeated by the following question, “But where did that come from?”
Only by finding something that exists outside space and time can this question be put to rest.
Oddly enough, if there were a theory of the universe that showed the universe is basically static, and does not change in size, shape, or mass, the problem would be solved. One could say that the universe has always existed, and therefore is “God.” However, we know that there is red shift in the universe, indicating that it is expanding. This forces us to take this change into account. Anything that is in a state of flux is not static, and anything that is expanding cannot be infinite, because if it were, it would already be taking up all the space it could.
Suppose we say that the universe just keeps expanding and imploding, over and over through the eons, and it has always been that way. If so, then why isn’t the universe (and earth) more balanced? On the other hand, why does it abide by certain laws?
