Science requires systematic observation, measurement and usually variation (often experimentally controlled); and, usually, iterations.
One datapoint outside such a system is not science.
You can’t even necessarily just insert a new datapoint into a pre-existing scientific sytem. The system itself may need to be adjusted, for example to test and account for biases that often occur due to how observations are made.
Isn’t a counter example just data, even though it’s just one case it’s still science
