And this is why your beliefs are relevant. Do you believe in a universe that sprang from a miracle? If so, you have no grounds to ridicule others for the exact same belief. If not then you have to explain how that could possibly be the case.
Wrong on all counts
One wrong set of beliefs doesn't make another set of beliefs automatically correct. They have to be proven on their own merits. This is False Dilemma Fallacy or false dichotomy.
Even if I believed in a universe that sprang from a miracle (which I don't) that is not exact same belief. That is comparing apples to oranges just like comparing Christianity to Norse mythogy or bullshit with dogshit.
The only common denominator is they all fairytales.
A tree in a forrest doesn't have to explain how it fell it just did. You have to prove it independently.
Likewise I don't owe you an explanation on behalf of the Universe how it originated.
