"The nitrogen in our DNA, the calcium in our teeth. The iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff." ~ Carl Sagan

On that note since we all come from stars we are space aliens ourselves. We just evolved in this particular body. I love our planet Earth! Gave us mj!

I do believe we've already made contact with them, not sure of how many different alien types individuals or groups have encountered. I'm certain the greys are one of them, but you know the government and doors kept confidential for a reason. It's a wonder all this time we haven't been colonized yet by higher beings, maybe our resources are primitive still. Or we are already colonized by the greys and the shadow government of the government is a front for them. Who knows... invisible strings...
