Yeah they do so much damage though.
I believe Creep is talking about the AE2 meteors which are part of world generation - while they
look like they've caused damage, the world is generated like that.
Now that said, I do remember a mod that added meteors which
did fall and cause damage, back in the Hexxit modpack - they even had bits which started off hot, and if you didn't mine them quickly enough would go cool and give you less useful stuff.
EDIT: The mod was called Falling Meteors, and is covered in brief
here.
