Who is the bald pale skinned dude in sj room?

He is the Space Jockey...

Really? Who's in the chair? Or is it a suit?

This has of course been discussed to death with many theories and assumptions as to who this guy may or may not be, because this is a repeat thread I am reaching for the keys, please look in the prometheus section of the forums for any of many open threads about this mysterious figure.
