Step 2 is a fallacy, the same that is used by God/Ghost/Bigfoot/UFO believers all the time. Saying something cannot be shown to be imposible doesn't demonstrate that it is possible.
E.g. I claim that inside a box that you cannot examine lives a leprechaun.
You not being able to prove it doesn't exist does not constitute evidence that it could exist.
