The most important reason anyone is an atheist

[Esquilax]

Lord Shiva was the first to introduce intuitional science.
Beside this what did he do?
He gave the Ayurvedic medicine.
He gave the 7 notes so the people could create music that help in their spiritual search.
He introduce the marriage system in a society in which women were used as objects.
He gave the asanas posture (yoga exercises).
He gave a system of moral conduct in a society in which the stronger abuse the weak and a lot more you could learn at the uni.

Thanks for your inquire anyway and sorry if i disappoint you.

So, remember when I asked for mainstream scientific sources, achievements, people and processes?

Why did you instead decide to give me a big heaping helping of unverified bullshit?
