The ancient Greek philosophers inferred the existence of atoms on sound principles and sound reasoning, granted that they didn’t know, and couldn’t know, very much about their nature, which knowledge was left to be discovered by far future generations. But this fact does not diminish, but only increases the status of their intellectual achievement, and properly leaves us in awe of them, and their time.
I have no problem with the Greeks, and accord them their due respect. But we've moved on. If you really want to see who nailed it thousands of years ago, look at the Indian Vedas, which describe the "spanda" or vibration of "Maya" or the unified energy field, which creates all manifestations. They could have litterally been describing the most modern theories of quantum physics we have today. And they also speak of advanced technologies of the past, including zero point energy and non-newtonian propulsion systems.
