But I think if there was any life from outer space around this exact planet we would know it already, so honestly I don't really believe that any of these seen UFOs have been actual aliens. Technically, we have no indication, nor any true scientific proof that life may exist outside of earth, or our solar system. The fact is, whatever force caused life to begin (which shall forever be a mystery) it is quite possible that those conditions caused life to sprout here, and that it has not occured elsewhere in the universe. The nearest star is 8 light years away (proxima centauri) and it has no planets, therefore nowhere for life to exist. The nearest star with planets is probably 50 light years away, and those planets may not have the right life-supporting conditions. Plus, if life was first generated here, it would takes millions of years for any vessel, be it comet or asteroid, to make it to the next habitable location, and all that time is in the lifeless, near absolute zero conditions of deep space. I believe it is entirely possible that no life exists outside of our solar system, and if there is, the chances of that life being as intelligent or more than humans is incredibly slim. Take the 8.7 million species projected to live on earth, only one out of 8.7 million is intelligent enough to do what we do. Now say there is another race outside of earth just like us, or more intelligent, why would they invest their resources and hundred of thousands (to millions) of year traveling across the expanse of lifeless space, only to reach earth, flash by in a few minutes, and leave? That is the question. That is why I think they don't exist. Lightspeed travel is impossible for living beings, therefore the time spent is to great for any intelligent beings to not stop here, and make contact, or at least linger to observe. I believe that there is no magical force that is needed to start life, but instead life can start anywhere where conditions for it are good enough. There are so huge amount of planets in the universe that surely somewhere there are many earth like planets with water and other things that have made life on earth possible. I can't see why life couldn't develop in those places too. Amount of planets is simply so very huge that there must be probably millions of planets out there that could support life. Also maybe it doesn't even require exactly earth like conditions to happen, who knows. Also some forms of life surely could sustain travelling speed of flight. And like said I don't believe that there are or have ever been aliens on this planet, but I highly believe that they do exist somewhere. Just any planet with water, right resources and right distance from nearest star/stars could have life.

The problem is that once at the speed of light, and object's mass becomes infinite, therefore, any life form would be instantly killed because its mass would be so great that it would exceed any organism's limits, and therefore, it would die. A Whale dies on land because its mass is too great to be supported by anything other than a liquid fluid.

But that is the great mystery of life, not the conditions, no, those are things that can happen anywhere, any time. Rather, it is how the structure of the first life form, a simple single-celled prokaryotic cell came to be with a coil of DNA with the right codings for life, ribosomes, a cell wall, cell membrane, plasmids, and cytoplasm, and how that structure began to function as a single living form that was capable of taking in nutrients, processing them, and reproducing itself by mitosis all at once. I'm by no means denying the existance or possibility of e.t life and it starting in unrelated places, but that once miraculous event in which the first life form started, what made it start, and how it survived is the mystery. We look at artistic devices that people make, magnetic coils that change shape through their own inertia and opposite polls, and how that thing can only assume the exact same shape once; how now to snow flakes are alike, how not a single non-living thing in the universe can form and create more than formations in a nearly identical fashion (let alone as something that is routine like reporduction) more than once (that one time being the original, or an example of that thing, i.e. a mountain). It is with this that I say that through the extreme, harsh, and unpredictable course of mother nature, that it is entirely possible that whatever caused life to begin one day, may only have happened once, and perhaps we are lucky, because that one original cell survived, for if it didn't, we may well all be just atoms floating in oblivion.

Thats my two cents. Not denying the possiblity of e.t life, just pointing out my opinion based on what I have learned, and what seems like 'common knowledge' everywhere else.
