I assume nothing. Regarding the laws of physics, I told you, that I can look back ~5B yrs ago and beyond. Why did you ignore that and make the above claim? Do you realize you're making claims about what you know nothing about?
Because you cannot make such a claim with any certitude. You can only do so by making a number of assumptions and hoping you are correct. It is you who are "making claims about what you know nothing about." Whatever you have as a compass for determing what is worthy of acceptation, it is no more worthy of scientific consideration than the Koran.
