lets get real,okay.if there was no such thing as aliens visiting earth why and i mean why does are government go to so much trouble to debunke it..there is just too much proof out there staring  us in the face....granted there are some people who need proof such as a ride around are planete in a spaceship,with aliens,and then some would say well i was dreaming or somebody gave me something to make me see that..in other words some will not believe  nomatter what  ,now for one,are race has gone from horse and buggy to the moon  in just over a hundred years..can you imagine a race thousands of years older,oh but of coarse if we dont have it , can not imagine it,it can not be, right..we would be like prehistoric man vs todays mankind to them..there are things we can not even imagine out there and around us..if they were watching us would there not be a base of operations say, mars or the moon,(is that why we have not been to the moon,we know something, )it could even be possible they have been here all along,(the missing link,in are genes) is all this and so much more that hard to swallow or  believe ,,can you imagine what a higher race of being are saying about us,,they are not ready to see us,they would panic and possibly destroy themeselfs,,we can not give them such knowledge it would destroy them,,it comes down to this,are we ready if it did happin..any race watching us would think what,,they are bloodthirsty they kill each other for every reason religion,drugs money,land,color,race,,,i bet they could talk for days about serious flaws in are race..and in the end one alien says to the other,,they are not ready,give them another hundred years,,then,well see...
