My suggestion was that given the language used by the poster we might have someone actually seeking information and not just slamming down a gauntlet, so maybe you might want to readdress the ABRUPT answer you gave.
In fact, if you will quickly flip over to page 70 at this site (http://msmd.gov.ng/Bitumen%20Bid%20Memo.pdf#search=%22athabascan%20tar%20sands%20recovery%20machinery%22 ) you will find some statements suspiciously like those used by that earlier poster ~ almost like we have a young person reading about the Nigerian tarsands and getting confused with the discussion on the fosils in them.
I just love Google.com's search capabilities. DOn't you?!
FWIW, most of the Alberta and so far all of the Sask oil sands oil has been extracted through steam. The lower the Bitumen level the more steam is used as an extraction method.
The OP made an unsubstantiated claim based on a low knowledge level and presented it in such a way as to imply her information was as valid as any other.
"...so maybe you might want to readdress the ABRUPT answer you gave"
What was ABRUPT about my post?
The OP has been more than a little shrill in her rejection of anything evolutionary and has shown little to no desire to temper her posts based on her obvious knowledge level. If she wants to learn I would be happy to contribute what I little I can but she needs to recognize her ignorance for what it is and not pretend to a certainty of knowledge she doesn't have.
I have no problem with people with a lower level of knowledge in a given area than I have just as I have no problem with people with a higher level of knowledge.
