Rubbish.
How many people are there on these forums? 2,000? 5,000? 8,000? That is only a fraction of a million. One million is only a fraction of the world's population.
How many people - Christians and non Christians - on these forums believe the moon landings were a hoax? I have never done a poll, and I doubt you have either.
Say we're working with a figure of 5,000 forum members - for the sake of my maths, only. You do a poll asking about the moon landings, unusually, every single member here answers and the answer is that 1,000 people think they were a hoax. (And I'm being generous; I don't think you'd even get into triple figures.)
That is still only 1/5; 20% of people here.
Even if every forum on the internet did a similar poll, got ALL their members to answer and got the same result, that's still only 1/5 of people.
That doesn't even include those who aren't online, or who are but have better things to do with their time that to answer a poll about something that happened over 50 years ago.
Put simply, you have no way of knowing that "most of the world's population" now believe that moon landings are a hoax.
