"Never say never". We don't fully understand spacetime yet. Particle entanglement seems to defy time and space, for instance.

Now, this does not have to be this way, because if there was no BB and space is not expanding, then we are merely looking at the universe as it is, except that everything we see is old, since time is defined by lightspeed c, thus it takes time for c to get to us. If I took an arc of space, say 20', in any direction, along that expanding cone of space I would be looking back through time until I got back to one of two things: 1. either the light fades out so it is no longer visible, though the 20' arc now covers a very wide area, whether or not BB happened; or 2. there are no more stars and galaxies because they had not yet come into existence, since 380,000 ATB, so that BB did happen. For now, we cannot answer with certainty which it is, though I have my issues with the latter.

In the case of "1.", it may make a difference whether or not BB happened. Since you can only see light coming your way, and if the universe were ageless and infinite, you should see light everywhere if the universe had somewhat even distribution of galaxies. You already know about this paradox. [This reminds me of...."if we had some ham we could have ham and eggs, if we had some eggs".

In case "2.", you will see light in the form of microwaves - the CMB. Redshift is a key factor but there are others as well. The evidence favors BB.
