Other Worlds in God's Creation

For all the galaxies, there is God.
For every planet, there are plans.
For all that hunger, there is hope.
For all that reason, there is responsibility.
For all that love, there is laughter.
For all that do not, there is mercy.
Do we wonder why?

Why are men and women so self-centered that they believe that humans are the only ones in the universe that God considers to be His children?
