in math they use a lot of approximations to do calculations like limits -> infinity. It's a good enough approximation that is almost unrefutable. Also, who has more ego, we are the winner of 1 in 10e30, or there is way more winners.

The mass in the observable universe is considered to be 10^53 kg. So nothing is going to infinity when it comes to life made from matter (or energy).

I am not sure how to talk about things outside the observable universe. If light speed provides the ultimate limit for causality, this outside might as well not exist, from our perspective.
