Its one of those things, Its very difficult to prove they do exist, however its impossible to prove they don't. What i however find the most difficult is separating the real photos or footage from the fake. The genuine people from the nobody's who make something up because they just want a bit of attention. I do often look up at the stars and wonder about other intelligent life, I personally think its out there. And its very possible they are watching us with interest. I wonder what they must think of this mad world we live in and weather they can make any sense of it. Do they understand how most the wealth is owned by such a small percentage of the population while large percentages of the population live hunger and in poverty. Do they understand why we poison are air, while chopping down the things that make air? I bet there wondering how we made it this far.
