I love this! I don't think earth gets visitors like this, if any at all. There has to be something "out there" but if they could find us, if they were looking at us and seeing us now, we would be long dead by the time they got here. Light speed and all that crap. Though I did read that they managed to teleport light. Which sounds pretty cool.
I don't understand why the general consensus is that aliens are so much more advanced than us and can travel through time and have these huge super advanced space craft. I also don't understand why they all look the same big head big eyes blueish purple skin. I believe more that there are strange creatures that lurk the deepest oceans and the darkest woods. There is plenty of completly foreign places right here on earth were the odd could hang, like skullbrain.
