If there is "greys" out there, then there must be many other life forms out there. MANY! Why is it they would come to this tiny planet in the middle of universe nowhere to study a being that is far less advanced than they would have to be to get here....let alone find us (which would be nearly impossible) As far as the photographs go, did you take them? Do you know who did? How do you know for sure they are real? Have you seen aliens such as those?

The air they can breathe is thin when on our land they do need a breathing apparatus.

ok since weve seen so many pics and vids of these grey WITHOUT any types of clothing its safe to assume they can breathe our atmosphere. Maybe they can adapt their bodies to it. Like I said we need to know the biology of the entity.

Well, we landed on the moon in 50 years coming from the first ever flight of an airplane, now immagine them being billions of years more advanced then us.
Im not saying that any have visited or continue to do so still, but that i stated the what i though were some reasons for them to come.

Landing on the moon is one thing. The nearest star to planet earth barring the sun is many many light years away. Radio transmisions traveling at the speed of light since the beginning of this century have not made it there yet. And we are talking the next star. There are billions and billions and billions of stars in this galaxy alone. There are billions and billions of galaxies. I just find it improbable that even an advanced life form would be able to find us. That is if there is life far more advanced than us. Nomatter how the universe started or didnt start, we have all had the same amount of time to evolve from the beginning.

There is also the theory of bending space as Einstein said.
MAybe someone qualified could talk us through this theory.

uh... hate to break it to you buddy, but there's basically a sphere of radio noise going out from earth that's about 100 light years around. so that means there's a plethora of stars that radio waves from earth have come to. so yeah, basically... you're wrong... also, there are older stars and older galaxies than our own. our solar system is about 4.6 billion years old, our galaxy is much much older...

are you talking about string theory?

Regardless of the age of the Universe, ETs exist and have visited/are visiting Earth. There is so much proof....drawings on cave walls from prehistoric times, the Face on Mars, UFO coverups, multiple sightings and videos, etc.

You're right about the 100 light year radius, but that doesn't mean the aliens can pick our signal. The energy of the radio signals has been spread over 4*pi*(100 light year)^2 m^2. That means there is only very little of the original signal left. The aliens could be pick our radio transmissions, but it's probably to faint to be noticed. I read a book once that calculated how much energy was needed to send a radio burst that was still distinguishable at the other side of the milky way. I think it was a few times our suns output.
, I don't want to offend you, but Einstein was already dead when string theory was invented. More about string theory here. The theory triplesod means is General Relativity. It's very different mathematically (4d differential geometry, tensor mathematics). If you want to learn it, I suggest you start with Special Relativity, which is a lot easier. Free text books at an undergraduate level and at graduate level.
