King Charles's snubbing of Archie and Lilibet proves they don't exist is a conspiracy theory that has been circulating online. There is no evidence to support this claim, and it is based on a number of logical fallacies.
First, the claim relies on the assumption that King Charles would not snub his own grandchildren if they existed. However,
there are many reasons why King Charles might not have publicly acknowledged Archie and Lilibet's birthdays. For example, he may have been trying to avoid furthering the rift between himself and Prince Harry. Or, he may have simply been following protocol, as the Royal Family does not typically publicly acknowledge the birthdays of grandchildren who are not in the line of succession.
Second, the claim ignores the fact that there is plenty of evidence that Archie and Lilibet do exist. There are photographs of them, they have been seen in public, and they have been mentioned in official statements by the Royal Family.
Finally, the claim is based on the idea that the Royal Family is somehow trying to hide the existence of Archie and Lilibet. However, there is no reason to believe that this is the case. The Royal Family has never denied the existence of Archie and Lilibet, and they have even released photographs of them.
In conclusion, there is no evidence to support the claim that King Charles's snubbing of Archie and Lilibet proves they don't exist. This is a conspiracy theory that is based on logical fallacies and a lack of evidence.
