You can have the last word if you like, but I think I've reached the end of the road you are wanting to go down.

...yeh, good idea.

So lets boil this down to original question: is cremation biblical? In my humble (and I believe, very accurate )oppenion, If...

God created man out of the dust of the earth and it is to the earth that it returns when the spirit no longer dwells in it...

...then I see nothing in terms of prohibition in the Bible when it comes to the assortment of that "dust" when it returns to the ground.
