I have been seeing and reading where scientist are changing their theory that nothing can go faster than the speed of light and in fact they have even shown that the speed of light can be slowed down through crystals or something. What may ultimately be their way of transporting to one place or another will be mind blowing for us today no doubt if it really is happening. As the saying goes, with God all things are possible, I will not rule it out of the realm of possibility.I do believe there might be a possibility of life on other planets in the universe, but I doubt any of them have visited us. Even if they had the capability to do so and even traveling at light speed it would take too long for them to get here. Do you honestly thing they would travel all that way and just fly around and go home? Even if Earth was not there final destination, they would at least get out and stretch their legs. I can say without any doubt there are none in our solar system, because we would have evidence by now.
