Absolutely, without a doubt! I just recently watched a show on The History channel dealing with correlations between stories in the Bible and UFOs/E.T.s as interpreted by todays ideas. Particularily interesting was the story of Elija being taken into a "chariot of fire", drawn by 4 great white horses across the heavens, never to be seen again. The interpretation was a spaceship, and it occurred to me that if people can believe some of the more colorful stories in the Bible with absolute conviction, why is it so far-fetched to believe in spaceships and E.T.s?
E.T.s have been on this planet from the beginning; they are among us today, and they will be here when this world ends..hopefully to transport humans to another place and survive the destruction of Earth.
