Your reading comprehension is different than mine. I’m not going to take time to find the way more than several verses that refute that – just start with the thought that he is infinite and we are not.
You don’t know that. There are reasons to believe that he is. Is he omnipresent? Yes. If you haven’t yet, watch enough of this interesting NOVA video posted earlier and elsewhere to be able to visualize spacetime slices. God is omnipresent in them. That implies he is omnitemporal as well:

ETA: Corrected link just above. ↑ Outside of the U.S., the video may be inaccessible, but there is a transcript available on the page. (Streaming might be available in Canada?)
