Probably the fact that they've "discovered a bacterium in California’s Mono Lake that uses arsenic instead of phosphorus in its DNA. Up until now, it was believed that all life required phosphorus as a fundamental piece of the ‘backbone’ that holds DNA together. The discovery of an organism that thrives on otherwise poisonous arsenic broadens our thinking about the possibility of life on other planets, and begs a rewrite of biology textbooks by changing our understanding of how life is formed from its most basic elemental building blocks."
Plus the fact that a new study says there are 3 time more stars than they thought. 300 sextillion stars. That's 300,000,000,000,000,000,000,000 stars. http://wwwery.com/10298-more-stars-in-sky.html
Looks like they're warming us up for disclosure to me.
