There have been numerous claims in the past predicting the end of the world. None have come true, so far. But that hasn't stopped an online Christian group from renewing the dire forecast.

Chris McCann, leader of eBible fellowship -- an online Bible group - has released a five-series podcast with detailed explanations as to why the apocalypse would occur and how the "world would end on 7 October 2015". His group had earlier claimed that the world would end on 21 May 2011, but have now revised the date, claiming that the earlier occasion "was the beginning of a prolonged period of judgment".

McCann has used verses from the Bible as the source of his warning and has insisted that previously "the world was inundated with water, but this time it will be annihilated".

"May 21, 2011 was exactly 7,000 years from the flood and was the equivalent day the flood began, as God brought the flood waters of the 'seventeenth day of the second month' of Noah's 600th year," he said in his podcast.

This time, the world would be destroyed by fire, The Guardian reported McCann as saying. "According to what the Bible is presenting it does appear that 7 October will be the day that God has spoken of: in which, the world will pass away."

However, his doomsday claims have been slammed on social media. Check out Twitter reactions below:
