They proposed theories. The concept of Maya and Brahman can be related to the quantum wierdness that scientists discovered today.
The question is how come rishis got to these advanced concepts without any apparatus? All we knew was that they were in forsts meditating.
Is it possible that when we see inwards, we can unveil many misteries? Is quantum wierdness the end of discovery? Can we not go beyong it?
So many misteries. So many questions. How can we fix the truth? What is absolute truth today may not be so tomorrow. But in the process, is it not our honesty to leave that doesnt make any sense at all like superstitions and profets?
Until proven to masses, anything is just theory. Not truth.
