The subject claimed to have spoken with one of these people, who told them that a group had left in what 'looks like the inside of a larger boat.'

The administrator told the subject to go along on the journey and report what they saw.

'Impression of a really crazy place with volcanoes and gas pockets and strange plants—a very volatile place. It's very much like going from the frying pan into the fire,' the subject said.

'The difference is there seems to be a lot of vegetation where the other place did not have it. And a different kind of storm.'
And that folks, is how Raquel Welch came to Earth.
