NASA Openly Admits That Alien Life Exists And...

Who are the Star Trek-The Next Generation fans here? Might be most of you, right?

Well, if you have watched its episodes then you must have come across to the question which says, "How come no matter where we go out there, aliens look roughly like us?" Apparently, in science fictions, such role are played by humans, but it has biased us toward expecting E.T. beings to have legs, arms, head, and spins as like humans.

And, now NASA has also stated that it might be true that extraterrestrial could already be among us and we are not aware of it. Seems weird? Check the details here!

Aside from extra-terrestrial beings visiting our planet:

Scientists are trying to learn about many different E.T. races tinkering with our DNA over millennia and also about the truth behind the life of E.T. beings been on earth.

No doubt, if we separate the list of human beings and other living organisms than the list of insects and animals would be long enough.

There are less or no chances that E.T. beings look like us, or even be recognizable as living creatures to our bounded insights. Do you think the same? 

Not as human beings...

...but extraterrestrial beings might be floating, prowling, or flying over your head. We just don't know if they are living among us or not.

At the NASA Innovative Advanced Concepts Symposium, Boston said,"It's not like that you can walk into a new environment with your lovely robot on some other planet, look at the ground and go gosh it's life! Instead, it's gosh it's blue something, and it's got a copper signal, and I don't know, and then you have to investigate."

Identifying either something is viable or just a weirdly shaped mineral is a huge challenge for astrobiologists looking for extraterrestrials. Boston said that E.T. environments analogous to Earthly conditions are usually limited to things like sulphuric acid caves. And, on earth, these places are toxic for human beings, yet they are capable of hosting an enormous diversity of microbial life, including the life forms biologists can't identify.

Boston pointed out that we can't identify these creatures on earth, then how are we going to recognize aliens when we find them?

Boston said, "I would sure like to solve this or have one of my students solve this before I drop dead, but I don't know if that's going to happen. This is the magnitude of what we are trying to do."

The problem: the shortage of genetic tools.

Boston also stated that they haven't yet invented necessary technology to identify such bions. While trying to discover new microbes, genetic tools don't always provide clear answers. She also asked next generation of innovators to come up with better technologies to recognize life in whatever form it appears.
