From the purely scientific standpoint, I am unaware of any hard evidence that extraterrestrials have been here, and am equally unaware of any hard evidence that they have not. If a bacteria transported here by a meteor survived to divide on earth, is that an extraterrestrial? If a soup of protein precursor molecules arrived the same way and combined on earth to form 'life'; are they extraterrestrial? If a key ingredient of primordial life was added to the soup by one or more meteors, would that life be extraterrestrial? Since all the constituent parts of the Earth's environment originated 'in space'; surely extraterrestrials have been here; because we are they?
