You might be interested in two books I recently read:
Ratcliffe, Hilton, The Static Universe, Apeiron Press. [Argues that the universe is not expanding.]
Lerner, Eric J., The Big Bang Never Happened, Vintage Press.
The "evidence" for an expanding universe is the "red shift" of light from distant stars, presumed to be due to Doppler shift. That's discussed in Arp, Halton, Seeing Red, Apeiron Press. Arp argues that the red shift is due to other factors, not recessional velocity.
These authors are bucking some ideas that have been considered "established" for a long time. Read the books and see what the authors' counter-arguments are. I found them very interesting, but they're outside my field, and I'm not ready to say yes or no.
Im not terribly well educated. I do know that something needs to be present for something to BANG...to explode....as per the big bang.
eternal existence is clearly beyond my capacity to comprehend but the impossibility of something exploding from nothing..is not.
