the largest logical fallacy among many that this article suffers from is that alien species would necessarily need to be technologically advanced to reach us. This probably comes from another flawed line of thought that aliens need to be like us in some way (hence requiring things like figuring out how to survive radiation, last for long periods without food and so on). This doesnt really make sense since on earth itself there are species that can do things we humans couldnt do (cockroaches can cope with tremendous amounts of radiation for example, and bacteria that live near geysers etc - thrive at extremely high temperatures). So why isn't it possible that an alien species that just about figures out how to ride a rock in space and doesnt really need all the advancement that we need to survive - comes floating by planet earth and decides to check us out sometimes?! Don't back up a lack of imagination with flawed logic ;)
