Actually by the word "pagans" he is refering to those people who lived during the lifetime of Prophet Muhammad(pbuh) and who practiced idol worshipping.
Yes you are right, the present buddists and hindus can also be termed as "pagans" since they practice idol worshipping.
Pagans are actually polytheists who believe in more than 1 God.

Panth you say that you donot have the actual evidence regarding the existance of God, than what do you think about the verses of the Qur'an that I have quoted above? Have those verses of the Qur'an come down to us from a superman or heman?

As I have already mentioned their are more arguments in favour of Gods existance rather than arguments against His existance.

What type of Scientific evidence do you want for Gods existance?
