10 Reasons Alien Life Really Is Probably Out There Somewhere

Although most people are skeptical, alien life, whether advanced or merely microbial, most likely exists somewhere in the universe. Most scientists agree that this is almost certainly the case.

That doesn’t mean that gray aliens with large heads and big eyes are out there abducting people, but it is almost a statistical certainty that some kind of cosmic microbe or “space insect” is going about its business somewhere in the universe. With that in mind, here are 10 reasons why alien life probably does exist.

Simple Law Of Averages

Although actual numbers change all the time due to new discoveries or even the downgrading of a planet to a dwarf planet or moon, it is largely agreed that there are billions of planets, solar systems, and galaxies in the vast reaches of the cosmos.

When you consider that space is “never-ending,” so then must the possibilities of other planets be never-ending. In turn, this increases the chance of life existing somewhere in the depths of space.

Even if we believe that only 1 percent of these planets harbor life, it is still a huge number of cosmic bodies with life. As is the case here on Earth, each planet is likely to have life in many forms. That is a lot of aliens out there. Of course, until firm proof is offered, even the probability of alien life will be downplayed and dismissed by some.

Water Is Everywhere (Relatively Speaking)

If water is the key to a cosmic body being able to host life as we understand it, then that’s good news for those who feel they will be vindicated in their beliefs one day. Relatively speaking, water is everywhere in the universe, although often in the form of ice.

Not every time, however. There are many moons—within our own solar system, to boot—that have almost definite signs of liquid water.

Aside from differing views on whether liquid water is present on Mars, several moons of the gas giants Jupiter and Saturn show signs of possible liquid water. Perhaps most notably, one of Saturn’s moons, Enceladus, appears to shoot huge jet streams of water vapor and ice particles into outer space from cracks in the icy surface. This also suggests significant geological activity that could provide the right conditions for life.

Life Could Be Based On Other Elements

For the most part, mainstream science concentrates on locating life that requires the same conditions and building blocks as Earth’s life-forms. However, it is possible that life could exist on another planet that requires a completely different set of conditions and would truly be “alien” to us.

Again, the possibilities are endless, but perhaps there is a being that resides in liquid or gas form? Or, if a given planet has an atmosphere comprised of hydrogen or nitrogen, for example, might its life-forms primarily be based upon these elements? Or perhaps one of these elements is abundant in liquid form, and so it takes the place in alien life-forms of the water in our bodies.

This theory is supported in part by the increasing number of living organisms (known as extremophiles) that thrive in otherwise hostile conditions on Earth. It is not that much of a stretch of the imagination to believe that a similar organism might exist in the freezing conditions of Mars or even the hellish inferno that is Venus.

In short, we may not have found alien life yet because we may not know what we are looking for. Just to take it a thought further: Alien life could even exist in a form that is undetectable to us in terms of what our eyes and ears can see and hear. It really could be a case of we don’t know that we don’t know, but we don’t know! Yet!
