uhh there is a rock you seem to be stuck under here.
The big bang theory is now the most widely accepted on origins as universal observations have eliminated all the competitors. Even a multi-verse universe still requires a beginning or beginnings...

That is, after all, the very essence of science: to be able to test a hypothesis and get predictable results.
