Should Humanity Try to Contact Intelligent Aliens?

[Times Roman]

There's a theory that the aliens who have visited Earth use an advanced propulsion system that manipulates distances by 'folding' space in half, thus greatly reducing the distance from A to B. Bob Lazar (although discredited) had a similar 'experience'. He claimed that aliens use a type of fuel in their spacecraft's called Element 115 and at the time - in 1989 - he was laughed at. It was only recently (2006 or so) that scientists managed to create this matter, although in small quantities. Interesting ideas.

if an alien specie so advanced they could use gravitational fields to not only curve space, but fold it as you describe, if they wanted the Earth, there would be little we could do to stop them. But I doubt there would be any reason to fear such individuals. We would probably possess nothing of any value to them. They should/would be able to survive on any planet. To continue, they may only be partially biological, or none at all. And if they were sufficiently evolved/advanced, they may not have bodies as we know them at all. Comprised of light energy. And then, for all practical matters, they would truly ignore us. In theory, they could be all around us and we wouldn't even know it.

Maybe we have nothing of significant value to them but then again, as it has been shown in films, it could be a scenario where they need something as simple as water or food. I'm more inclined to think they've already visited for reconnaissance purposes and our planet is simply unsuitable to sustain life for them.
