The universe appears "old", but it is still less than 10,000 years old

[Anomalocaris]

You seem to think a simple conclusion drawn from an experiment can be cast into serious doubt by the expedient of contriving a much more convoluted alternative explanation, without any need to accompany the alternative with even a vague proposal of how the alternative can be tested and the simpler explanation excluded. In this you are more like a Wordorf, trying to find wiggle room for a hoax, or at least a figment of fancy, than a person with a genuine inclination towards finding explanations most likely to be true in light of available explanation.
