Theosophy traces man’s evolution through countless ages and many worlds, and tells us how that evolution has been guided by Elder Brothers who passed through the same experiences untold ages ago. It shows us, too, how during the present stages of evolution these Elder Brothers take an interest in us, and in different ways impart some of their wonderful knowledge to those who earnestly seek for it.
Oh, right... There is one difference. Ancient astronaut theorists don't believe in human evolution.
