Well evidence that there is a God is like compared to the air. You can feel it, but cannot see it. That's how God is c:
You can brown townyze the chemical composition and behavior of air with the wide variety of instrumentation produced by technology. In some conditions you can physically view the atmosphere when it is heavily condensed by a fighter jet flying at supersonic speed. Not that it has anything to do with religion, but you can, for all intensive purposes, "see" air.
I'm sorry to hear that and forgive those who acted greedy :/. I even say sorry to God single night, because we sin everyday and you cannot avoid it (thats why us Christians have spiritual battles constantly)
Greediness is part of human behavior. We're organisms that psychologically always want better houses, more money, more food, etc. It seems sorta pointless to establish some moral dogma that forbids something completely unavoidable by every person on Earth. Of course in Judeo-Christian religions there's always the solution that praying and repenting for your greed will remove your transgressions, which seems oddly convenient for Evangelists. "Just join us and your greed will be forbidden". It reminds me of those Scientology pamphlets I find on the street that convert people to Scientology by warning them of the dangers of the multitude of "toxins" we consume on a daily basis(listing vital items like 'bottled water' and 'food').
