the bible has a lot of truths within it, it can also be mis-interepted and has lost original meanings down the years of time and translations
funny you should mention about the bible/UFO/ET corolation
in the book 'intelligent design' there are many references with the bible and the ET's and could be more to the truth than we know or want to accept
take some time to read it, see if it makes sense to you?
