"correlation does not imply causation" must be a strong contender.
Correlation does not prove causation, but it does suggest it.
Only when that model is further validated correlation suggests causation.
Yeah that's what correlation means?

No! It suggests causation already. There may not be causation but it definitely suggests it.
For example if I find that eating fast food correlates with BMI then there's a pretty clear suggestion that eating fast food causes increased BMI. It might not be the case! But it's clearly very suggestive.
1. There is little correlation, but there is actual causation (e.g: a cricle)
2. There is correlation, but it turns out to be a fluke later during validation.
So, yes. It suggests but in both cases I'd rather continue checkcing
