One thing that seems odd to me, is how come our technological advancements grew by leaps and bounds in the 20th century alone? But for hundreds, and maybe thousands of years, our rate of "evolution" was very slow.

Nobody still knows for sure how that came about, unless the governments got it from somewhere. Like say, an alien spacecraft that crashed? Roswell, anyone?

Cos there seems like a quantum leap in technology during the 20th century compared to the previous 10 centuries. So maybe alien spacecraft did crash into earth and the governments (like USA) managed to reverse-engineer the technology.

It's hard to explain the fiber optics, lasers, hologram technology, LED and many others which sprang up so soon after WW2.

Also, scientists cannot explain how come ancient monuments like Baalbek in Lebanon, where the ancient temple had many HUGE stone pillars weighing 800 tons. Even today, it is impossible to lift them using our technology. Just Google Baalbek.

Unless, they had some kind of outside help?

All questions with no satisfactory answers till today.

Not saying it's fact but only a possibility. In less than 100 years, we have space shuttles, sent men to the moon, nano technology, stealth technology, the internet, microchips, nuclear tech, particle collider, and what not. In less than 100 years, we have sprawling metropolises with huge skyscrapers that would have terrified even people just 150 years ago....Such amazing changes in so short a time span.

Perhaps such huge growth in < 100 years is not coincidental? Who knows......I'm just throwing something out here. Did we achieve all this alone, or is there something else to it?

Even past civilizations show such unexplainable technology like the Baalbek temple for one. So, I just wonder if aliens are here on earth, all this while, and been in contact with some humans...or we reverse engineered some high tech stuff from their crashed space ships. Truth can be stranger than fiction

I don't care too much about the Nobel Prize, ironically, one of the current holders of this peace prize has just expanded war in Afghanistan....it's just a title. But I never said those winners are liars?
