WOW the proof of the extermination of 75% of life on Earth.

"When we proposed the impact hypothesis to explain the great extinction, it was based just on finding an anomalous concentration of iridium—the fingerprint of an asteroid or comet," said Alvarez. "Since then, the evidence has gradually built up. But it never crossed my mind that we would find a deathbed like this."

Not mentioned is that this can happen again, at any time!!!
