I said that the more than science answers, the lesser questions there will be for which God or religion would be the deduced answer. The reason I believe this is because scientists are always doing research and trying to find answers to such questions, whereas religion is stagnant and usually are based on scriptures written thousands of years ago. Religious heads do no attempt to gather more answers, but instead fall back on their scriptures for meanings or answers. Science is ever progressing and considers all evidence uncovered by humans. Science, and subsequently technology, is what has driven our civilizations' progress for centuries. And this leads me to believe that science will play a more important role in the future than what it is doing today.
As for disproving religion altogether, I see it as water filling an empty glass. As an when there's more water being poured into the glass, the empty space in the glass becomes lesser and lesser. While the glass may not be completely full at present, based on the continuous flow of water, it's evident that the glass will be completely full in the near future. I may be wrong, and there might still be a small space left. But only time will tell. And this time may be centuries or millenniums.
