Where are the aliens? List four reasons why aliens can not be found, they may have come to Earth
Science of the Universe
The universe is so big that there are likely to be many ways for a civilization to exist, and even other alien civilizations exist in ways that are far beyond our current human perception.
It is possible that they will not exist in the universe in the form of our human appearance.
So is there an extraterrestrial higher life form in this universe that is similar to our human race or not?
If they exist, where are they?
Such a question was also asked by Fermi in the last century, and later became known as the Fermi paradox.
Today we will list four reasons why humans cannot find aliens.
The Earth Rarity Hypothesis.
Scientists who support this hypothesis believe that there is no life form similar to us humans in this universe except for our Earth and that Earth is a rare celestial body.
Only the region between 13,000 and 33,000 light-years from the center of the Milky Way is the habitable zone of the galaxy.
If life is to exist on other planets, the planet must have a suitable star that is about the same age and size as our Sun.
The planet would also have to be near the habitable zone in the star system.
And there must be a planet like Jupiter and Saturn to withstand the impact of an alien asteroid.
On top of the planet must have the right temperature, the right atmosphere, the right concentration of oxygen, the right time of light, and so on. The combination of conditions is harsh.
On the contrary, in the vast universe we live in, the Earth is a rare object.
Looking for another planet suitable for life in the universe, looking for another planet similar to our Earth, is like finding a person similar to yourself on Earth.
It's almost like a non-existent probability.
Humans were the first intelligent life.
Scientists who support this hypothesis believe that there may be many life systems in the universe, but we are the first intelligent life systems like us humans.
Humans are unable to contact other life systems precisely because their civilization is of a lower level than ours, limited by distance and the level of technological development.
Restricted by time and space, which is why we humans can never detect them.
The Great Filter Hypothesis.
Scientists who support this hypothesis believe that throughout the history of civilization development, any civilization has to pass through a barrier.
This barrier is then referred to as a threshold in the history of civilization development.
Most civilizations have been unable to cross this threshold.
The filter that the dinosaurs faced was the catastrophe caused by the asteroid's impact on the Earth.
And the big filter we humans face in the future is the outbreak of nuclear weapons war.
Including some other alien civilizations in the universe, the filter they face is likely to be other large disasters in the universe or other limitations of high-tech technology.
If this theory is true, then have you ever reflected on the question, where are we humans at up to now?
How many years from now will we meet our filter?
Likely, higher alien civilizations have already visited Earth.
Scientists who support this hypothesis believe that it is very likely that higher extraterrestrial civilizations came to Earth a long time ago, but at that time there were no people on Earth at all.
Why do you think so?
If we all reflect on the history of human development on our planet, Homo sapiens has evolved only 50,000 years ago until now, and the written history is only 5,500 years old.
50,000 years of history is only a brief moment for the entire universe.
Scientists who support this theory also reasoned that it is likely that we were not yet born when aliens came to Earth precisely because the existence of humans in the universe is too short.
A history of more than 50,000 years is not even worth mentioning for the 13.8 billion years of the Big Bang.
In the 5500 years before written records, we have no way to verify what alien events have happened on Earth.
What is everyone's opinion about aliens in the universe? Why do you think we humans are unable to find aliens? Leave your opinions in the comments section.

Human Evolution and Climate Change
The Question An oft asked question relates to how humans and every other species on the planet will or will not adapt to the new environmental conditions that climate change will quite probably (and arguably already has) impose across much of the globe. For other species the answer is fairly obvious, they will either adapt or they will perish. As has been the case throughout all of earth’s history, evolution through natural selection requires that those with the traits that are best adapted to reproduce will do so and so pass them on, especially when pressed by changes in the environment. Many argue that the changes we are seeing or will soon see as a result of climate change are occurring too rapidly for many species to adapt. In essence that evolution cannot keep up with the pace of change. Mutations simply cannot occur frequently enough to supply a wide enough variety of phenotypes of different varieties to allow for at least one that can survive the new conditions any given species may find itself in. Rapid changes are the hardest for the longest lived (excluding microorganisms), and slowest reproducing creatures to deal with, and they face the greatest threat of massive population decrease or even extinction. I happen to think that adaptation can happen much faster than is typically believed, but am not naïve enough to think that even a greatly accelerated adaptation or mutation process will be enough to save all or even most animal species from the threat of habitat loss or change brought about by global warming.

Main Character Immunity
Click Combat armor damaged but still doing its job, still have ammo, can move though the knee is giving me some grief, that's the door I have to get through, I know I'll need a passcode, but before that I have to get through a ton of bad guys between here and there. I check my battery pack – yeah, decent power, but I'm going to need a distraction. I turn to my team...

Change
She looked at her son. He was a man now really. Moments came when she saw glimpses of the boy he once was but rarely and they were snatched by her when he didn't know that he was being scrutinised by someone trying to make sense of who this person was, what he would become.
