Earth is massive. It is full of life-friendly resources and has an ideal climate. So why can’t other extraterrestrial races live with the rest of us here on the blue planet? Or are they already here with us?

A person is capable of many things but limited in others. The human sense and hearing allow us to recreate only a portion of the reality the universe hides. Compared to alien species, we are highly limited and unable to perceive realities past what we know and understand.

So if we can’t tell these things apart, like a camouflaged animal perhaps, what chances do we have at finding an intelligent alien specie that is hiding among us?

Kune asked this question and said extraterrestrials might already be here. They may already be living with us on the Blue Planet and walk alongside people undetected.

There are over 7.6 billion people on Earth and about 6.4 billion of them are humans, but there could be around 17 million aliens living among us, a physicist has said.

This number is based on the assumption that aliens would have to inhabit the same area as humans do in order for contact to be made. But this does not mean that they will come into contact with each other just because of the sheer number of people on Earth.

Just because two human beings are standing close enough to each other doesn’t necessarily make them aware of each other or have any interaction, so it’s safe to say there could be millions — if not more — aliens living among us if they’re spread out across Earth rather than in one place.

Sufi, however, is not convinced that there’s a single alien race.”If you look at the way the world works, if you’re talking about a hierarchical arrangement which we talk about in terms of nations and countries and things like that then it makes sense to say there’s a single alien race,” he said. “There is one set of rules but they’re playing out across different countries.”

Despite the fact that there are millions of aliens on earth, we don’t know their existence. We have no idea how advanced their civilization is and neither do we have any idea what their life is like.

The physicist, Professor Stephen Hawking believes in a possible existence of intelligent life in other galaxies and universes. He believes that during the period of universal expansion, planets might be able to develop advanced civilizations just like ours due to the fact that they are often surrounded by hydrogen atoms which can be used as fuel and building materials.

Thus the probability of marrying an alien is around 50%. Many have already been identified as they attempt to impersonate humans, but there are still more out there.

So why did they settle here? Why did these alien races choose to live here on Earth?

The reasons for their arrival might be as simple as wanting to live somewhere other than their home planet because their planet has already declined or they were preparing for conquest. Regardless, these creatures have proven peaceful and capable of mutual understanding with humanity. The physicist thinks the creatures will continue to seek our company more as they stay on Earth
