Why is knowing any history important? The Western Empire's collapse in 476 is considered a major and important event in world history, but it's knowledge is of conceivable value to any future human endeavour. We value it because we like knowing where we came from. To the question of obviousness - lots of things are obvious but wrong. It was obvious that Earth was at the centre of the universe. It was obvious that heavier-than-air craft couldn't fly. It was obvious that the aether existed. Studying obvious things is important.
