Not at present. All life on Earth appears to have evolved here, and it's all related.
Alfred Wegner developed the theory of plate tectonics, not a theory of a shrinking Earth. The Earth is not shrinking and no scientific theory has ever proposed that it is.
Meteorites containing ices bombarded the Earth during formation.

Darwin's observations supported Lyell's theory of ancient earth because he theorized that geology evolves the same way animals did!
There is no particular religious belief that just generically claims that absentee aliens created us. However, there is a concept known as "panspermia", which is a scientific theory (or hypothesis, depending on one's sources) as opposed to a religious belief. The theory basically proposes that life did not originate on Earth but rather came here in the form of microorganisms or chemical life-precursors from somewhere outside the earth. Naturally, as this is a scientific theory, it is open to falsification and evidentiary support. So far it hasn't been falsified, but the support for it is not conclusive either. It remains a theory of dubious utility until more supporting evidence can be found.
