There are things that have no answer except an Omnipotent and Eternal God. I humble myself and except that. YOU can’t be certain and can’t answer some BASIC questions about the science you trust. You just think you are smarter than someone like me.
That's why there's a difference between passionately inquisitive men like Lemaitre, who spent his life dedicated to science AND religion, and guys like you who use religion to be intentionally incurious.
