AGREE
Bottom line ... there are LOTS of things people believe in without any proof, like real proof. We can hear stories about all kinds of things whether religion, aliens, Big Foot, Yeti, mermaids, dragons, Santa, fairies ............ but that doesn't make any of it true. So we are all free to believe in whatever we wish to believe in to make us happy.
The arrogance comes because it is contradictory, whether you follow a religious or scientific beginning, to believe this massive indefinite universe was created and yet only one small ball was picked to be inhabited with creatures of all levels of intelligence.
