You have no idea of the difficulties inherent in the "not enough time" (6-10 thousand years) hypothesis in explaining the world we see. No doubt this is a conscious decision on your own part not to know some things.

The only difficulty would be for you because it would involve God.
But please, let us keep focused on the topic at hand and not on personal attacks.
Who could have made the world looking old. Last Thursday.
Please provide us with detailed reasoning on this important subject, that supports your hypothesis on this specific case.

Horse manure. The difficulties are enormous, and have nothing to do with a god or the lack thereof.
First, there are literally thousands of observations in geology that are inconsistent with the possibility that they were all formed within the timespan of only a few thousand years.
Another problem is that the biodiversity of humans, for example, is orders of magnitude greater than that which could arise in only a few thousand years from a starting genepool of either one man and one woman (using the Adam/Eve scenario) or one man and four women (using the Noah scenario).
There are more shark teeth in the sediments of the ocean than could possibly be produced by a even a ridiculously large overpopulation of sharks in only a few thousand years.
Etc. etc. etc.
