All developments in human society have been the results of necessity. Grinding stone, wheel, language, marital institution and governance etc. etc. grew out of sheer necessity. Religions (as practiced by different population groups) were no exception. It is the man who made religions and not any God, Allah or Bhagawan. Why cow does not have a God? Is she not entitled to a God? She does not have a God as she cannot contemplate and create a God for herself. It is as simple as that.
From Second millennium BC to present days, there have been a total of 9 major religions and 53 cults/religious philosophies propagated in this world. Interestingly all nine major religions (Judaism, Hinduism, Zoroastrianism, Confucianism, Buddhism, Taoism, Jainism, Christianity and Islam) are old with Islam being the last to come during AD seventh century. For next eight centuries, no new religion came in to being. Thereafter during each of fifteenth, sixteenth and seventeenth century, one new cult/religious philosophy came up. In eighteenth century the figure rose to three. The whole of nineteenth century saw eleven new cults/religious philosophies. Lastly the number of new cult/religious philosophy rose maximum to thirty six in twentieth century. The pattern is very meaningful and objective. Try to imagine this picture as a graph on the wall.
Why after AD seventh century, no new major religion has come? The simple reason being there was no necessity. In other words, religion was a requirement of human society in old times. After the initial lull of eight centuries following advent of Islam, development of religion was replaced by development of cults/religious philosophies mostly out of some major religions. Actually the cults/religious philosophies are only apologies for religions. All these latter cults/religious philosophies have very small followings in international context. This fact means that human beings had left behind need for any religion. When religions have become redundant, God has no relevance.
In twenty first century, the world has become a global village. More emphasis is given on scientific development and socio-economic progress of human society. Theoretically religions were to make good people and good human society. But in actual, all have miserably failed. Today we don’t need any self defeating and bogus religion to be good people. We can be good independent of any religious affiliation. And in absence of religion, God just does not exist anymore.
God (or Allah/Bhagawan) has died as we don’t need him anymore.
