Your sentence would be grammatically correct, if you said it this way

I think the mentioned sentence can be considered from two points of view:
1) the size which refers to the world we live in
2) the life span which you've mentioned
According to the first one I think the sentence would be fine.
Synonym"Life is not that small as it seems to be."No. I'm not sure exactly what you mean. Maybe this: "Life is not as short as it seems to be."
