Remember how Q mentioned the Matrix? And said it's like a garden?
Earth is Eden
We're the flowers.
(((They))) pick us.
Riddle me this. How many humans are alive today? Almost 8,000,000,000?
If 100 people have 100 kids, you could say that the population of that sample doubled in 20 years. Except say half of those kids die, so those kids needs kids first. Now the population took 40 years to double. Let's be generous and say it takes 75 years for a population to double. This accounts for all disease and war possibilities. It's extremely conservative.
Now, half 8 billion 25 times. You get to around 200 people. What year is it? Is it 198,000 BC? Or is 200 AD?
