Strange Sounds in Costa Rica and My Thoughts – Annunaki

Seismologists ruled out ground movement in Costa Rica after strange sounds were heard. These sounds then were heard in the Ukraine and in Canada. I feel the West Coast will be next, especially Phoenix, AZ. I speculate that they are coming from UFOs and it's possible that aliens are among us right now. I will talk about the CDC and the Zombie Preparedness blog that was issued in July 2011. Could this be end times as mentioned in the Bible?
