There is no generally-accepted evidence that this occurred. The "alien visitors" theories concerning UFOs and alleged abductions are scientifically unsubstantiated. It is possible that non-intelligent lifeforms may have reached Earth in the form of organic material thrown into space by collisions of other planets or stars.

Why did God create life on other planets besides earth?
Scientists say that life can be expected to have evolved on other planets, wherever the environment is not so hostile that life can not be supported. They say that in this vast universe there must be many such planets that can support life and that some are likely to support intelligent life forms even more advanced than humans. Whether we believe that our God created the life on other planets is a matter of human faith. No doubt any intelligent life on other planets will never have heard of Earth's gods.

How can the Earth support life when other planets cant?
The biggest reason is water. Astronomers think maybe there really may be traces of water or ice on other planets, but Earth has an abundance, perfect for us. Also, many other planet's living conditions are not suitable. Some planets have EXTREMELY hot hot hot or coooollllddd ccccoollllddd weather that we could not live through. There is not fertile soil or animals to eat (we probably wouldn't be eating aliens :P ). And atmospheres aren't as nice, no substantial protection from the sun's rays and gravity not as strong. There are also some more detailed answers but these are mostly the main ideas why the Earth support life when other planets cant.
