Data was released from the Kepler telescope's first 43 days of operation yeilding 750 planetary candidates. Not all will be actual planets owing to false positives from star spots, binaries and other factors but you can bet your boots there are a bunch. My basis for skepticism has always been based largely on Astronomy. Tell me it makes sense that Yaweh created the cosmos then waited 13.7 billion years at least to choose a group of scruffy goat herding primates on a tiny planet lost in an unimaginably vast universe to be the chosen people! Alrighty then!
