Life is common in the universe.

Well, it's common on ONE planet in the universe.

Life originated on earth several times

There is no evidence for this. None.

and on Mars, Jupiter and its sattelites and on the sattelites of uranus 
and on venus and the moon.

Oh. You're one of THEM.

Intelligent life is the most common form of life

Judging by what you've written, intelligence is
quite rare and not at all common.

there are several other earthly specieas that came close to human 
intelligence until we killed them off one as recently as AD1300.

Indeed...... QUITE rare.
