In the literal way your question is worded, yes. The entire solar system was formed from the ashes and ejecta of bodies and events elsewhere in the galaxy, acted on by universal forces. Earth and everything on it was, therefore, "effected" by outside forces.
Reading your post, I see you mean "affected."
No.
Has the universe harbored life other than on Earth? Almost certainly, in uncountable locations and varieties.
Did such life
A) have the technology to surmount the obstacles of unimaginable distance and insane energy requirements to traverse the stars?
B) exist at the right point in time, i.e. between 4 billion years ago and a couple million years ago?
C) exist at the right point in space, i.e. within traveling distance of Earth?
D) find Earth among billions of other rocks floating around out there?
E) have any interest in mucking around, seeding primitive planets with protoplasm, or throwing rocks to kill the dinosaurs?
The likelihood of A through E being true ranges from probably not to essentially zero. For the answer to your question to be yes, all five would have to be true. The likelihood of that is too stupendously tiny to be worth considering.
If you're talking about a supreme being, a god, the answer is still no. There is no observable thing anywhere in the universe that lends any credence whatsoever to the notion of a supernatural creator. Gods are merely people's way of coping with things they don't understand.
