Evidence

After that remarkable meeting amongst the extra-terrestrials, Rex went back to its own planet.

In no time, the extinct creature met Jessie and Woody and explained to them the situation.

The cowboy shivered, "Oh my god. They are pointing finger at us. What are we going to do?"

Jessie tapped on the shoulder of her friend and said, "Don't worry. Should we first ask the more fundamental question: Are we doing that bad?"

"Why? Of course we are. The mortality on this planet is highest in the solar system!" The green dinosaur and the cowboy yelled together.

"Yes, it is the highest - but, is it significantly higher than the other planets?" Jessie went on.

"What do you mean?" The other two appeared confused.

"Alas, if the difference is not statistically significant, why should those mollusks living outside the solar system make such a big fuss?" The cowgirl explained, "After all, since they are so fond of evidence based medicine, and would not allow the introduction of a new drug unless the benefit is very much significantly better than existing ones, why should they demand actions for a so-called problem if they could not prove there is actually a problem?"
