Why do so many people refuse to believe things that have happened in the past even when the truth is staring them in the face?
There are those who refuse to believe the horrors of the Holocaust in the concentration camps in Germany in the Second World War which saw six million Jews murdered took place.
There are those who refuse to believe the Apollo Moon landings really happened.
And now, according to recent figures, four per cent of people believe Elvis Presley is still alive, 36 years after his drug-riddled body finally gave up on him.
In all three cases – and there are no doubt others which readers will be able to bring to mind – there is not a shred of evidence to support their claims.
But they nevertheless make enough of a fuss for them to be picked up by some cranks who jump on their bandwagon and haul it to the front of a media campaign.
Let’s shoot down the nay sayers.
The Holocaust horrors are well documented with photographic evidence it would be impossible to fabricate.
Similarly, there is enough film footage of the Apollo moon landings – as well as the classic Apollo 13 film – as proof.
And as for Elvis, if he had still been alive today he would be some kind of superman – although to be absolutely sure he is dead, Mr Pendle will check he is not working at his favourite chippy when he calls in for his tea tonight.
