Aliens, Truth, or real? The answer to that question is a definite, resounding maybe.
Since the dawn of time, it is probable, if not almost certain, that aliens have existed in some form or another. While their likelihood on earth is considered rather low, the chance of alien life in the universe, somewhere, is considered so high it's almost statistically certain. It would make less sense that, when chemicals are effected in such a certain way, that they wouldn't respond the same way everywhere in the universe, such as with the right temperatures, ingredients, and so on. While many put forward the goldilocks zone as a reason as to why life might be rare, I personally believe it's a lot more common. The goldilocks zone only determines the temperature of a planet, on it's surface. 200 miles beneath a frozen ocean surface could be much warmer, just like how the core of the earth is warmer, and certain planets, such as Neptune, if they were just slightly closer to the sun, could likely support life, and may already in some small form of another. Not only this, but various animals, termed extremophiles, are capable of surviving a much wider variety of temperatures. Even large animals, such as tardigrades, otherwise known as water bears (such as the one in my profile), are known to exist! In fact, their genetic lineage is incomparable to any other species on earth, and science has had trouble classifying them as a result, which means, they may in fact be alien life, themselves!
However, the prevalence of intelligent alien life, at least comparable to ourselves, may be less common. While it would be difficult to explain why we haven't been contacted yet, in geological times, 1 alien visit per few hundred years would be incredibly common, which means we may have been visited by aliens as of yet. In fact, we may have mistaken them for Gods, which is where many of the biblical stories come from. In fact, just a single UFO touching down would have been dismissed as a fake or hoax, and thus garnering widespread belief for it would be low, even if it had occurred.
Aliens may not be allowed to interfere with our development. Like with Star Trek, where they aren't allowed to interfere with fledgling aliens, so wouldn't an intergalactic coalition of planets be allowed to, either. They may be forced to leave us alone, until they're ready, and so they may just be monitoring us, for the most part. A hyper drive bends light and other forms of radiation along with the fabric of spacetime, so if you could theoretically build a hyper drive, you could become virtually invisible from nearly all forms of detection, except for maybe the lense that views earth.
So, this is a no holds bar, unrelinquished view of alien life, where I will not judge your opinion! For the most part.
What is your belief on aliens?!
