For me, the belief in the existence of Extra Terrestrial life forms is not a matter of faith, its a matter of statistics. With all the Trillions of Galaxies and stars out there, there is no way that a significant number of those are devoid of orbiting rocky bodies. And furthermore, there is almost no way that given enough time, some of those rocky bodies satisfy enough of the basic conditions necissary to begin life. To say we are the only ones, would almost be to agree by default to the religious ideal of Creationism.

Ghosts, spirits, souls, ESP and the like are a different matter entirely. All my knowledge and opinions on these things are based on experience and supposition. We have no way to measure or detect the kinds of energies, frequencies, and/or wavelengths that these "phenomena" may be operating on. However, given the money, I would invest a significant amount of it towards finding the answers to these questions.
