All this is future weapons, you think about it, once WW3 kicks off ( if ever ) then these things will pop out and the "enemy" would think WTF !!! just like hirroshima <sp.
There has to be something awe inspiring to stop any threat to world peace, some of the technology and weapons they have now are beyond belief....
As for aliens and such like, your all looking in the wrong place.... look down not up.... they are deep in the sea !!!
How else can you explain flashing fishes and whatnot !!!
Just my thoughts.....
