I never understood this stuff... I WANT to believe in aliens... Seriously. That would be sh*t hot to have aliens visiting us.
Only problem is, that in todays day and age, we have 1.5 trillion megapixel cameras and such. Seriously, a bottom dollar digital camera at Walmart would be at least 2-4 megapixels these days... Enough resolution that even with a 'cheap' camera, if you uploaded it to your computer and zoomed in with any generic photo software, you'd be able to see very fine details on these 'craft'.
So why is it that every time one of these pictures surfaces, it has to look like it was taken with a 1972 Polariod camera, fully zoomed out with a sh*t stain on the lens?
