All religions are under threat as people clamber for democracy in countries where whole societies revolved around the dictates of the prevailing religion. From census data taken in 85 Western nations, it was found that the number of people ticking "unaffiliated" is increasing. Though the formula predicts total extinction of religious belief it is doubtful that this will actually occur. Even when a religion is outlawed people tend to go underground with their beliefs. It comes to life again when circumstances improve.
The thing is, we will never really know if there is a God. Many go to church as "insurance", just in case there is life after death. Religious books give us answers to the questions in life. Science may "disprove" such things as Adam being created just five thousand years ago but these books are so complex that a reader will find an answer somewhere in there amongst the complicated and confusing text.
