🫡 Really

Common knowledge You don’t have to back up absolutely everything you say with evidence (or you’d soon run out of wordcount to advance your own point properly!). Some things are common knowledge. That could mean that a fact is just generally known by everyone, and not disputed or in doubt. This could include:

•facts such as London is the capital of the United Kingdom •well documented dates such as the start of the First World War in 1914 •H20 being the chemical formula for water •things which everyone knows from their lived experience, such as the sky is blue.
