As'salamu Alaikum dear brother,
Thank you for sharing the link with us. I've noticed that many of the references that the author gave were too broad. He didn't give any specific chapter or verse references. He only gave names of people or books. It's like saying the Bible says such and such and such. But the Bible is very broad. It's got well over a thousand pages in it.
Also, the Vedas, according to the author, were written 6,000 years ago. We as Muslims have no problem in believing that there are possible remnants of Divine Truth out there from previous Divine Revelations. There could very well be Scientific Miracles in the Vedas. But this doesn't mean that the pagan hinduism is valid, or that all of the Vedas is the Pure Word of GOD Almighty. We can't say for sure that the book and even the accurate Scientific claims in it are the PURE Word of GOD Almighty. Always keep that in mind when dealing with any Text outside the Glorious Quran, dear brother. This also includes our Hadiths' Texts. They're not Divine. And above all, they're not the Holy Words of Allah Almighty. Only the Glorious Quran is.
I hope this helps dear brother. But like I said, the author failed to give real references.
Take care,
Osama Abdallah
