I'll take an altered version of #1:
1. There is no known God. According to a strong preponderance of evidence we are exactly like the animals just exeedingly smarter. Even though the prospect of death is something all life has to live with our strong and complex minds help us cope with that fact as well as develop technology to lengthen our lifespans and provide a better life for us all. With this in mind we remain open to any evidence that suggests that we are not alone and we are greatful not to live in the darker times of our species history such as the Dark Ages.
If there is no God it needs to be proven because at this point in the game our species has resources like no other time. If God isn't going to come save us than our saviour, by immediate necessity, becomes humanity's greatest challenge. There will always be people stuburningly holding onto false hope much like someone who burns alive in their house because they don't want to believe it happening to them. These types are best left ignored as we mobilize this planet's inhabitants in opposition of possible human extinction.
