How can something that had a beginning in time (13.7 billion years ago) and expanded with a finite speed be infinite with no edges ?

I know that this is the implication of the LCDM, but still I find it very counter intuitive. I've always preferred to think of the universe as finite but curved with no boundaries (kind of 3d sphere with a curvature in a 4th dimension).

The only way that i can digest the flat infinite idea is that by "infinite" we mean that the outside is irrelevant and therefore it does not exist, at least within the realm of cosmology. And if there is no outside, then the universe is infinite.

is this an acceptable interpretation of the flat infinite idea ?

Thanks in advance
