Answer:
cavemen
Step-by-step explanation:
Cavemen were real, while Adam and Eve are part of the Bible, they aren't confirmed to be an actual historic event. If you want to be technical and include the Bible, then Adam and Eve would come first, because according to the Bible, they were the first human beings. Keep in mind, the authenticity of the Bible's events is controversial, this would mostly be up to your own religious or non-religious opinion. If you don't believe in the Bible's stories, then cavemen would be your answer.
