Speculation about inhabited worlds beyond Earth dates back to antiquity.

With the discovery of numerous new planets what we asking here is ( are we being kept in the dark) when it comes to any evidence that Earth has had a Extraterrestrial life, or alien life(colloquially aliens), visit. A life that originates from another world rather than Earth.

( Such life might range from simple forms such as microbes to intelligent beings)

The answer is.

No extraterrestrial life has yet been detected visiting earth.

There is no verified physical, chemical, or biological evidence that an alien life form has ever visited Earth.

However organisations like- SETI (Search for Extraterrestrial Intelligence) are continuously scanning the stars for technological signals.

And there are numerous reports of all types of crafts hovering over nuclear plants etc.

As to how an Alien might view us is as you can imagine totally out side our current comprehension.

In fact, scientists recently updated their official “post-detection protocols” to outline exactly how the world would be notified if we ever did find verified evidence of alien life.

If they (that is Extraterrestrial) are attracted by nuclear energy, with billions of smartphones cameras on earth that there is not one photo of a life form that qualifies as Alien. I suppose is the strongest argument that we are alone in the universe.

But if you take the universe ( never neighbouring universes) it is inconceivable that we are the only life form.

When most people think of our galactic neighbor, they think of the Andromeda Galaxy. It is a massive spiral galaxy similar in size to the Milky Way.

Our nearest galaxy is andromeda 2.5 light years away.

A light-year is the distance light travels in one year (about 5.88 trillion miles).

The light we see from Andromeda today left that galaxy when early human ancestors were first crafting stone tools.

Andromeda is actually moving toward the Milky Way at about 250,000 miles per hour.

In about 4.5 billion years, our two galaxies will collide and merge into a giant elliptical galaxy.
