I think there should be a human day. A Day where humans can look at each other with empathy and understanding and recollect how we got here, who we are, and what we are. Also actively act on advancing the human race. The possibilities are endless really.
Look what happens when we forget about our history, or achievements, or mistakes. Then again, look what happens when we help one another. Great things are possible, if we act on and become what we think we are.
