for some reason, i believe the world we're looking at is the world we live in but in 20.5 light years away. The universe is tricky science, many unknown elements can create delusion or even something we can't explain in our current language!
I must agree with Waspie (which is of course not too hard to do all the time...

).

This really makes no sense what so ever. Apart from anything else this planet is totally different from Earth, with a different type of star from the sun so how can it possibly be the same world we live on?
We do know some things about this planet, you know?
We know the following:
1)It's about 120 trillion miles away (i.e., out of reach).
2)It exists in a zone which makes its surface temperature range that in which liquid water
could exist.
3) It's orbital period (year) is ~13 Earth days (~4% of an Earth year).
4) It's mass is likely in the range of 5 times that of Earth.
5) It's radius is probably 1.5 times that of Earth's.
6) It's gravity is between 1 1/4 and 2.2 g, depending on its composition (which is not known yet).
7) It's approximately 4.4E9 years old.
8) It likely experiences tidal forces that are ~400 times stronger than the tidal forces of the Moon on the Earth, and it may in fact be tidally locked, with one hemisphere perpetually facing the star it orbits.
9) It is orbiting a star which is an M Class dwarf...at a distance of ~7 million miles. (the Sun is a G Class star... a very different animal, which is of course located ~9.3E7 miles away from Earth (~13 times farther away that Gliese 381 c is from Gliese 381) .
There is alot we do not know about it, but from what we can ascertain through established astrophysical methodology, it should be apparent that this planet is not the Earth...whatsoever.
The science of this is somewhat complicated and , "tricky", as you say, but the science leads us to knowledge, not belief. And, although we actually know very little about this planet, we do know that it is not the Earth in any way, shape, or form. There is no delusion here, and we can explain some rudimentary information regarding this remarkable discovery in plain English.
It is not the Earth--20.5 LY away. It is Gliese 581c, a very different place, whose only similarity to our world is in its calculated average surface temperature range.
Beliefs about this obscure world are insignificant, and irrelevant to knowledge. What is significant is the level to which astronomy has advanced to.
Want to be awed?
Rather than consider obscure beliefs, consider this:
We have derived this scientifically verifiable, although obviously rudimentary knowledge about a planet that is 20.5LY away from us.
That means that we have been able to gain what is actually substantial knowledge about a world which equates to an object the size of a pea...located approximately 400,000 miles away from the Earth.
Now that's something to be awed about!
