Not true, since we are more sophisticated than a cat or a dog or a
plant or a rock, then more is expected of us.  Out purpose in life is
to advance the human species so that it is capable of leaving the
Earth in some form to colonise the Universe.  Any alien life that we
encounter along the way will become our friends.  As I have said in an
earlier article, war between two sides that possess nuclear weapons
will not occur, since the result of that war will be Mutually Assured
Destruction, or MAD for short.

God has a plan for all of us.  This plan can be found through
meditation, prayer and/or conversation with others.

Don't you want more of a legacy than memories (in the minds of others)
and dust (which you will surely turn in to when you die), and since you
have children, allowing copies of your genes into the gene pool?
It is only by becoming one with the Universe that you can truly
leave a better legacy than this.
