I believe they spoke Anglo-Saxon, also known as Old English. It was a Germanic language which evolved into Middle English and then to the modern form of English we know today. If you would like to read an example of it then check out The Wanderer, which was an epic Anglo-Saxon poem:

Unfortunately, recorded history didn't begin until the Roman invasion, in AD 43. No literature of pre-Roman Britain has survived, and no written language has ever been found, despite DNA-analysis of a human presence that can be traced as far back as 25,000 years ago, before the last Ice Age. So apart from the archaeological data, and assumptions drawn from what was going on in Europe, there's really not much to go on.
Certainly, the settlements on Skara Brae and particularly the Knap of Howar testify to a culture that existed from 3700 BCE, pre-dating the Great Pyramid of Egypt and even Stonehenge. But as to what language they spoke, nobody can say for sure.
Some believe the Celtic languages arrived in Britain around the 12th century BCE, however it is generally accepted the Celtic languages originate from the Hallstatt culture, which would place it closer to the 6th century BCE. Pictish, spoken mainly in the north, also existed during that period, but its origin is unknown and was considered extinct by 900 CE. While there were undoubtedly languages preceding this period, there doesn't appear to be any evidence of what they were.
So I'm afraid the answer to the question is "we just don't know".
Many historians have conlcuded that Britain probably had many dialects of Celtic languages similar to modern Welsh or Cornish.

The Romans influenced Anglo Saxon Britain in many ways. The first is the language. The Anglo Saxon language was a mixture of majorly Latin, some Celtic, and Norse. The Romans also left some materials that Anglo Saxons used to build huts and homes. They also converted pagan Britain into Christianity in the 500s.

No, King Arthur is not believed to have been an Anglo-Saxon. He is a legendary figure from Celtic mythology and is associated with the Britons, who were a Celtic people. The Anglo-Saxons arrived in Britain centuries after the time when King Arthur is said to have lived.

The Anglo-Saxons thought that an invasion from the sea was impossible because the sea around Britain is very rough. There had not been an invasion from the sea since the Anglo-Saxon one, and the Anglo-Saxons had probably forgot that altogether, meaning they thought the sea couldn't be crossed.
