Thanks for the input. I will be posting some definitions.
A thing's
material cause is the material of which it consists. (For a table, that might be wood; for a statue, that might be bronze or marble.)
A thing's
efficient or
moving cause[4] is "the primary source of the change or rest." An efficient cause of
x can be present even if
x is never actually produced and so should not be confused with a sufficient cause.
[5] (Aristotle argues that, for a table, this would be the art of table-making, which is the principle guiding its creation.)

Lets say we have Nebula. Gravity begins pulling the gas in to one region and forms a star. So the material cause is the gas, and the efficient cause is gravity. So the efficient cause does not have to be an intelligence.
Also how do you know that efficient causes don't need causes themselves? You had an interesting response however I disagree with the philosophy.
