We know perfectly well that the first real beers were introduced to Britian in the 14th or 15th Centuries, from Belguim. Prior to that, we had brewed beer without hops, which doesn't count.

Anone who thinks that we invented beer also thinks that the pale, fizzy, flavourless gnats urine created in great quantities by various 'brewers' is actually beer and that pale, fizzy, flavourless gnats urine called 'Bud' tastes better as it's imported. These people will be taken to a re-education camp, and serenaded by monkeys with banjos until they repent.
