Actually, given that you made the first claim in the newly restarted discussion/debate, you should be the first to cite your sources.
That would be proper debate etiquette.
If your source does claim something similar to "if the earth moves a mile closer or further from the sun all life will die" then it is science fiction because science doesn't claim that. That would be a logical conclusion--another part of debating that really doesn't need sources. Here's his logical construction (as I understand it):
Scoopy's 'science' source says X.
Science doesn't actually claim X.
Therefore, Scoopy's source isn't science.
Scoopy's source claims to be scientific.
Scoopy's source is in fact not scientific (see first conclusion).
Therefore, Scoopy's source is fictitious (i.e. not real, not true).
Scoopy's source isn't science.
Scoopy's source is fiction.
Therefore, Scoopy's source is science fiction.
Taz doesn't need any sources to claim your source is science fiction. You made a claim, so it is on you to support your claim. Until then, you cannot disprove the counter-claim.
So who's your source?
