No scientific proof
Prominent sceptic Dr Michael Edmonds, who is a member of New Zealand Skeptics, believes that it is extremely unlikely the world will end as predicted.
"As a scientist I never treat anything as absolutely impossible, but there is certainly no scientific evidence to suggest our world will end anytime soon. "
When the date rolls around he hopes it will be sunny so people can enjoy Christmas, says Dr Edmonds, Christchurch.
"And for those who choose not to buy presents because of the `impending apocalypse', (there'll be) some very disappointed children and grandchildren."
He believes the theory is based around a misunderstanding of the Mayan calendar.
"Most calendars when they run out we just buy a new one, but for some reason the Mayan calendar has taken on some sort of doom and gloom mythos.
"I think if the ancient Mayans could see the modern day doomsayers they would be rolling on the floor laughing hysterically."
The world is always changing, he says. New species emerge and others go extinct. He believes that the world will last a long time yet but whether humans are here will depend on how well we treat the environment and each other.
