If light takes so long to reach Earth, isn't the viewable Universe COMPLETELY different than what we are seeing?

Yes. Even light from the sun takes around 8 mins + 19 seconds to get to us.

When we see a star, we often see it from many, many years ago, so it's quite possible it doesn't exist anymore.

Not much we can do about it!
