I watached an interesting series of Ancient Aliens by Discovery Channel.

One of the episode I watched (forgot the link) is about Nazi and its advanced weapon, most of those top German scientist were captured after WWII and sent to America, the German guy who invented V-Rocket/Missile said their technology was actually from them (them being refer to aliens).

The more I knew, the more I tend to believe many religion gods or upper rulers in the past may be aliens. 

The universe is is TOOO huge, combines billions of stars in our Galaxy and there are billions of Galaxies out there!

So it would be crazy to say there is no other life being in the universe besides us.

“I’ll tell you one thing about the universe, though. The universe is a pretty big place. It’s bigger than anything anyone has ever dreamed of before. So if it’s just us… seems like an awful waste of space. Right?” from the Movie Contact.

One particular thing is Sir Frances Crick discovered the DNA in the 1960s and won the Nobel Prize.

Sir Francis Crick has the following theory:

“Life did not evolve first on Earth; a highly advanced civilization became threatened so they devised a way to pass on their existence. They genetically-modified their DNA and sent it out from their planet on bacteria or meteorites with the hope that it would collide with another planet. It did, and that’s why we’re here. The DNA molecule is the most efficient information storage system in the entire universe. The immensity of complex, coded and precisely sequenced information is absolutely staggering. The DNA evidence speaks of intelligent, information-bearing design.

Complex DNA coding would have been necessary for even the hypothetical first so-called’ simple cell(s). Our DNA was encoded with messages from that other civilization. They programmed the molecules so that when we reached a certain level of intelligence, we would be able to access their information, and they could therefore ­ teach” us about ourselves, and how to progress. For life to form by chance is mathematically virtually impossible.”
