What do you think the goal of humanity should be?

We should work to reduce conscious suffering and increase conscious pleasure. That's basically it.

Being worthy of interstellar visitors, integrating with our own biosphere, being Earthlings

1- Living together in peace
2- Making sure everyone if taking cared of

Creating a fair and just society

that's an easy one.....

given the fractious egocentric nature of our species my top goal would be:

having enough people on this earth who have some influence on the affairs of others .....

actually believe it's worthwhile to work collectively with one another.

helping those less fortunate , cash , food , a place to live , whatever

Becoming Members in God’s family

Just get along..
