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

[Optimistic Mysanthrope]

Even if a one way measurement of the speed of light doesn't give you a precise, to the nanometer measurement.

It doesn't matter, it is sufficient to demonstrate that it isn't infinite.

And that is all you need to debunk Lisles hokum.

No it isn't sufficient, that's the whole point. It's got nothing to do with the accuracy of measurements, it's about having to assume an isotropic convention in order to measure the one-way speed. If you read up on it, you'll see why it debunks absolutely nothing. In an anisotropic convention, time dilation is caused by a change position, not velocity. So if you synchronise two "clocks", you lose all certainty of them remaining synchronised as soon as you move them.
