(Well, lets see if my english is (still) good enough.)
Why don't we burn or freeze.
If consider the universe as unlimited, than even the most unimaginable thing WILL happen somewhere and sometime.
No matter how many "earths" end as burning globes or "snowballs".
I think the fact that we are able to live here does not mean
this world was made for us and only for us.
We just had the "big prize" in the lottery of the universe
