Where Are They?

Whenever someone talk about "GOD" I think of alien, I really believe in the Ancient Astronaut theory, I believe alien did played a huge role in our existence, who knows we might even be their descendants as most scientists believe, it gives me thrills and excitements whenever I think of the "SKY GOD" Did the alien really visited Earth in the past and started the spark of life? if so then why aren't they coming back to check on us? Maybe they did? 95% of the "UFO" cases can be ruled out as a hoax but its the remaining 5% that gives us the willies says "Dr. Michio kaku", Physicist. The "Roswell" the "Phoenix lights" etc... are they all for real?? each of these cases had somehow been explained or debunked by the governments as weather balloons or military flares.. but what about all the witnesses? and I have never heard of a weather balloon in a size of a football field and how can the military flares form such a perfect formation? It's just beyond my understanding, We really need to spend more time on the remaining 5%... well its really not that hard to believe that alien do exist. In "Dr. Frank Drake a Radio Astronomer's equation, it is estimated that the number of communicating civilizations likely depends on a number of factors which must combine to yield a habitable planet where life has a chance to develop to a certain level of technological know-how. These factors include the rate of the formation of stars like the sun, the fraction of those with planets, the fraction of Earth-like planets, the fraction of such planets where life develops, the fraction of those where the life becomes intelligent, the fraction of intelligent species who can communicate in a way we could detect, and the lifetime of the communicating civilizations. Dr Frank Drake's own current estimate puts the number of communicating civilizations in the Galaxy at 10,000. 10,000 intelligent communicating civilizations? That's just insanely thrilling!! so why haven't we heard from any of them? Maybe the distance between us is just too vast? This leaves me with tons of questions running through my mind, What do they eat? Do they have races? Do they have religions? Are we their descendants? Which level of technology are they on? Did any of the intelligent civilizations made contact with any other intelligent civilizations? And the biggest question is where did they come from? Perhaps the only way to find out where did we come from is to make contact with the "SKY GOD"?? If they're really inter-Galactic then they must be knowing the answers to all my questions, perhaps the only way to solve the "String theory" is to make contact with the Aliens? The Topic "Alien" has been one of my biggest obsessions in life, I really want to be around for the biggest discovery in human-race, I'm truely jealous for the possibilities.
