Assuming the first intelligent species of our Galaxy originated in the most remote region of the Galaxy, in the farthest corner away from earth, they would be approximately 73,000 light years away.  This is a distance of 411,503,775,886,980,000 miles, which is 411 million billions of miles.  A jet airplane traveling four times the speed of sound could accomplish this distance in 16 billion years. 

Much faster is our own 1970's vintage space probe, Voyager.  Launched in 1977, Voyager has broken through our sun's gravitational pull and is destined to travel deep space until the sun freezes over – or until some space alien intercepts it and learns to dance the boogie woogie from the oldies music on Voyager's phonograph "Golden Record." 

Careening through space at approximately 38,000 miles per hour,[1] Voyager will travel 73,000 light years in 1.24 billion years, provided it suffers no obstructions.  Likewise, space aliens could reach our planet in just 1.24 billion years, using nothing but 1970's technology.  Assuming they evolved 6 billion years ago, this means that they arrived in our solar system approximately 4 ˝ billion years ago.  At that time, earth was just beginning to form.  But let's say that the aliens paused for 10,000 years every 10 light years, in order to build a civilization on a suitable planet, which after 10,000 years would become so overpopulated that they would be forced to move on.  Even then, the number is not much different, standing at 1.30 billion years.  This is not based on the assumption that they made a beeline for us; rather, it is based on the assumption that they expanded in all directions from their point of origin, and that we are one of many planets they could have visited within their radius of origin, which enlarged as they traveled in deep space, stopping every few light years, and pausing until overpopulation of suitable planets forced them to keep expanding.

The Galaxy itself is 100,000 light years in diameter.  Using these same numbers, the colonization of the entire Galaxy, just by using 1970's technology, should take no longer than 1.8 billion years.  

It could have happened even more quickly.  We could get to Alpha Centauri, the star closest to the sun, with much greater speed, in just 20,000 years, if we used the gravity of a planet to "slingshot" spaceships toward the foreign star.[2]  Using gravity as a slingshot would greatly enhance the speed at which we could travel.  Using this technique, it would allow us to colonize the entire Galaxy in just 565 million years – this number still allowing for 100 million years of down time during which aliens enjoy colonizing suitable solar systems until they become so overpopulated that they must move on.  This technology is just outside our current capabilities.  If stupid apes like us can achieve it, how much more efficient would the big-headed aliens be?

By putting these observations together, we can construct a hypothetical history of life in the universe.  The universe was formed 13.7 billion years ago.  The first life-sustainable solar systems were formed between 13 and 11 billion years ago.  Since intelligent life evolved on earth within 5 billion years, it should do so at least as fast on other planets, and the fastest among them was probably even faster.  Therefore, the first intelligent species emerged no later than 6 billion years ago.  This species and its descendent species would have colonized the entire Galaxy within 1.8 billion years.  Thus, by 4.2 billion years ago, the entire Galaxy was likely populated with space aliens.  This is likely the latest it could have happened.

Hence, space aliens permeated the Galaxy before life even appeared on earth.  They have been with our planet since the beginning, and have played God with us since the beginning.  At this point, evolutionary science and religion should stop their bickering and just get married, because the gods are real, and they are the product of evolution.

 

The Fuel of Space Travel

     But where would the aliens get the fuel for such long interstellar journeys?  How light and compact would the fuel need to be in order to make the journey on a single "tank of gas," so to speak?  After all, you can't refuel while you are inbetween stars, so you need to carry a very large amount of fuel with you.  To be feasible, the fuel must either be extremely light or pack one heck of a power punch.

          The fuel needed would be the hydrogen isotope deuterium, and the process to burn it would be nuclear fusion.  According to nuclear scientist Freidberg, "It would take only about a pickup truck full of deuterium laced ocean water to power Boston for a year."[3] This is a perfect fuel.  Not only does it provide 96 million MJ per kilogram, roughly 2.4 million times the energy provided by the same amount of gasoline,[4] it also occurs in plentiful amounts throughout the universe.  Water in one form or another is known to exist not only on earth, but also on comets, Uranus, Neptune, maybe Mars, and several moons of the gas giant planets of our own solar system.  Recently, water in steam form has even been spotted on planets outside our solar system.  Just 30 light years away from earth, there is a planet with the same mass as earth which is known to be comprised almost entirely of water.  It is much closer to its sun than earth is, ensuring gaseous form on the surface.[5]  Therefore, water must be a cheap and easy commodity on the intra-Galactic market.  The fuel required for a nuclear fusion powered space ship is commonly available, very cheap, and packs a power punch powerful enough to justify carrying its weight around in a gas tank for thousands of years while traveling through deep space.

The creationist narrative in Genesis 1 is contradicted by many ancient Christian texts.  Instead of an Almighty Creator God, ancient Christian texts espouse that the universe is born from blind arrogance and stupidity.  The angels caused evolution to occur from species to species.  There are many gods, (or aliens?), and the Christian God is just one among them.  Satan the Devil writes scripture, and thus the Bible was polluted with Genesis 1.  Archaeology and modern scholarship demonstrate that Genesis is indeed corrupted.  Cavemen walk with Adam and Eve.  Esoteric prophecies reveal the coming of Christ, and also reveal the dark forces that govern the cosmos.  Such are the ancient Christian writings.

Science vindicates the truth of these ideas.  Evolution often happens too fast for Darwin’s theory.  Gaps in the fossil record indicate that some kind of unnatural force acts together with natural selection.  Astrobiology reveals that intelligent life probably evolved long before us.  The fossil record reveals strange clues that aliens abducted species and transported them across oceans, and that DNA from diverse lineages was combined to spawn hybrid species.  Evidently, aliens influence evolution, and they are the gods of the world’s religions. 

This is not fiction.  All these facts are thoroughly documented in the links above.
