My friends and I have been having a very long debate over whether or not it is possible for a highly athletic and agile man armed with a high powered chainsaw to cut down a fully grown, fully aggressive prehistoric woolly mammoth in single combat.

My friends all say no, that the mammoth would simply trample the man or gore him, but I beleive that if the man was clever, and continued to outmanuver the mammoth, he would prevail, because he could stay on the beasts' flanks, out of range of the tusks and trunk, and with his chainsaw, he could sever the mammoth's tendons in its legs.

Doing this would cripple the mammoths' legs, and remove its mobility, in which case it would be a simple manner to approach the wounded mammoth from behind and deliver a coup de grace with the saw.

So, what do you think? Could the man succeed in his cunning plan, or would he be no match for the woolly mammoth's might, and be obliterated in the proccess?

I'm not talking about recent experiments where subatomic particles materialized "out of nothing". Those were actually materializing out of the high concentrations of energy present in the chamber. That's cheating.

I'm talking about bona fide, entirely self-produced self-creation. The kind where there is literally nothing to work with, not even oneself.

Would a process like that require cleverness, magic, both, or neither?
