The point about language is a good one.
If you tell people there was nothing before the big bang they assume 'you mean a vacuum of empty space'. And no it means there was not even empty space. There was literally nothing. It is very hard for the human mind to grasp such a concept.
There are many things we don't know yet, but one can't then argue 'the god of the gaps' in our knowledge. Meaning many people will assert 'well if we don't know then that mean it was god'. No, it means we don't know yet, just as we didn't know what caused disease 300 years ago.
We do know the universe is 13.7 billion years old and there are hundreds of billions of galaxies, each with hundreds of billions of stars.
To believe in any god, you have to believe it was all put in motion and allowed to continue on for 13.7 billion years to wait specifically for humans to arrive or be placed on the scene. And all those other galaxies, stars, and planets billions of light years away are just stage dressing so 13.7 billion years later we'd have something to look at.
That is quite a leap.
Sincerely, thank you.
