Abandoning aether was NOT a "simple" answer. One you abandon aether, all manner of weirdness suddenly pops in.

Light being the same speed irrespective of observer is weird. Velocity dilating length and time is weird. Not having a preferential observation point is weird. Not needing a medium for transmission is weird. Not being able to agree on simultaneity is weird. etc.

Aether wasn't just something that a bunch of dullards clung to. You have to abandon some very long held common-sense understanding when you give it up.

That's my point exactly.
