I mean, if you can perceive time after death then all of our lives are incredibly short and closer to the life-span of the stillborn than that of any of the stars.

A baby probably doesn't even have an understanding of abstract relativistic concepts like long and short to make such a judgement, and in death it would cease being able to consider anything.

They had a lifetime, same as anyone else.

Does this mean life isnt short, but the longest thing we have?

You're missing the point of the quote. It's not a statement about perception; it's a statement about scope.

For example, there is more music that has been published by the music industry than it is possible to listen to before dying. You can't even come close.

You'd never master all the martial arts. You'd never visit every town on Earth... at least, not in any meaningful capacity.

Life is short if you have things you want to do. This is why it's important to manage your time well.

Time does not exist.

Time is a pancake.

Don't you dare go killing babies, and lives are effectively infinite. Just as the surface of a sphere is infinite. Long and short only apply when comparing one sphere to another.

"Long" can be logically/factually implied as everlasting, a lot, etc. Time has a value. The baby who died had (logically and factually) none of it. Therefore, you can't say the baby had a long life.

I'd imagine at most it was a time of comfort, then coldness, then finally to be never was.
