I think in fermats last theorem we have to do the work for powers which are primes or the factors of the power is the prime with the same value such as 4(2*2),49(7*7), Because for non prime powers such as 21 we have to prove only the cubic case or the case for fifth power & if we prove the case of fifth power alone then the case of power 25(5*5) or 125(25*5) is getting proved by itself.Similarly if we prove the 4th power case then the other cases where the factors of the power is only two is getting proved.
In the equation a^(n)-b^(n)=x^(n) or x^(n)+b^(n)=a^(n){fermats last theorem}One more thing is there in it that if "a" has to be even then either "x" & "b" has to be either both odd or both even and lastly we will see that "a" will always be odd to make "x" and "b" natural.
it is obvious as
a^(n)-b^(n)=c^(2)-d^(2) like
7^(3)-4^(3)=140^(2)-139^(2) &
x^(n)=z^(2)-y^(2) like
3^(3)=14^(2)-13^(2).
it is all for natural values of a,b,c,d,x,z,y & of course n.
Identify the primes.

when i was a child (12) i was playing near a canal, it was getting dark. i saw a red/orange glow.. i turned to see a tall figure.. arms stretched out like jesus on the cross.. but there was no cross.. the whole thing glowed red/orange with no features.. it lit the area where it hovered. i turned away n looked back but it stayed there for 5 mins or so.. i turned again n it had gone. ive never been so scared in my life. im in my thirties now.. i wish i knew what happened..

I asked this sort of question a few days back, but I'm still looking for an answer?
Ok here is an interesting one. What is your theory on this??

I have a theory about aliens; I believe that they are humans, who have come back in time after a few thousand years to see what led to the way they evolved,

There have been to many sightings and reports to not think that they are a part of this world. I mean they are said to come and take cows, water, humans, embryos, and other stuff, they leave crop circles that we understand, like communicating with us,

So my theory is that they are people evolved, and I think they mean us no harm, just that they now have the technology to come back and see what we are like and not leave any of their technology behind as it could be disastrous, and maybe just leave clues as to what we will be like in a few thousand years.

As with past languages, our languages will be lost and replaced with new ones, so they wont be able to communicate
