@RexRed,
Quote: How do I know? God told me ...
Weren't you a sworn atheist, or s.th. Or maybe you has convereted into jelous theist ... as a result of the discussion. Yet, you didn't answer the other questions.
BTW the subject of the statement 'without any purpose' may not only be individual. It may be a group of people, for example, a TV station, a whole country ... even whole species on a whole planet. How did you decide that in my comment 'we' means 'me'?
Do you know that right here, on this planet, right now, in 2013, there is a country in the world that has an annual economic growth of 9% ... and will lose as usual only in this year 3600 sq.km of grassland into desert?
On one hand you have economic growth of 9%, and on the other you have deforestation, desertification of the land, ongoing global warming, droughts and floods, depletion of the natural water resources, 30% of the tee crops dried, local greenhouse effect by increase of the CO2 on the surface ... collapse of basic relations in bionomics.
Does it worth it?
Do you think that this is an economic activity with a purpose?
Most of the world nowadays looks exactly like this.
