The establishment would certainly like us to believe we just got better at detection.
Either way everything has a cause. We don't just develop these diseases for no reason.
All you need to do is look around and see how many people get diseases nowadays. And then look at the ingredients in food, pretty much everyone of those
chemicals that is in 90% of the stuff in the grocery store causes some form or
cancer or other diseases.
1 in 4 people get cancer now? Thats tells you right there something is afoot.
Not to mention there are many old cultures who were completely disease free.
Cancer never existed, teeth didn't rot, the only death was caused by injury or
old age, aside from rare cases.
Look for yourselves.
No it's not that we got better at detection or put new names to things.
Despite what science and his-story tries to tell us, we aren't any smarter
now then we were back then. In fact we've been become technologically advanced but intellectually primitive as a whole.
