Extraterrestrial civilizations. What is your opinion?

I believe that aliens don't exist. The evidence is simple: for believers, it is written that Adam and Eve were the first people. No one else was created. Dr. Kent Hovind supports this version. For atheists, I will use two pieces of evidence:

1) (from Ganymede) - Haven't seen it - don't know.
2) Most UFOs have been explained and were either objects, phenomena in the atmosphere, or meteors. In general, thousands of explained phenomena confirm that UFOs don't exist.

Well, for those who need more, I won't "push" anything on them.
Let them believe. (winking smiley)
