Put simply, no.
Explanation:
All possible theories governed by our current laws of physics cannot even simulate the first few minutes after the Big Bang (extra information: the four fundamental forces were combined into one "super-unified force" and we do not know how it works).
The generally accepted explanation is that a singularity used to exist before it collided with something (itself or something else) and the Big Bang happened.
