There is no evidence though to support the speculation. The actual evidence doesn't support it at all.
You do know that circumstantial evidence is still evidence, right?
There is no circumstancial evidence either. A Force vision from an inanimate object is not a paternity test.
She could have been a youngling at the school.
She could be a Kenobi, given Obi Wan speaks to her, and technically he had that saber longer than Anakin and Luke combined.
You're taking the event of the Force vision via the lightsaber and saying that equals evidence of your speculation. The Force vision was a factual event, it is what it is, and that's all it is. It does not prove anything. For it to be circumstantial evidence, it would be need to be a fact that proves paternity.
I think you're confusing circumstantial evidence with direct evidence.
Circumstantial evidence is evidence that relies on an inference to connect it to a conclusion of fact. By contrast, direct evidence supports the truth of an assertion directly, without need for any additional evidence or inference. A paternity test would be direct evidence.
True enough about the two, but the circumstantial evidence has to relate to the question at hand. A Force vision has nothing to do with paternity, conception or parenthood, and in fact the Force vision has Obi Wan speaking to her by name, so even if I cede the point on semantics, it actually doesn't support Luke as father, it refutes it.
