Welcome to the forum.
im an indian guy in my late 20's
still a muslim and i am looking forward to what you guys have to say about Islam.
As TheRationalizer said, it is just another man-made religion. Everywhere on this planet (even remote tribes), humans seem to have a set of weird beliefs and rituals, in an attempt to explain and control various natural phenomena.
See the links in my signature below to get an idea what my views are. Basically the 'scientific method' is my way of determining what is true and what is baloney. I don't follow any sacred text or any other 'authority'. I follow the 'evidence'.
which part of the quran do you guys think is man made?
It's your job to prove that it is
divine. Every religion/cult/tribe claims their beliefs are divine. Why do you reject (several thousand of) them and settle with Islam? I'm sure their followers also derive a great deal of comfort and satisfaction from their religion, but that doesn't mean they are true.
