All cells have at least a cell membrane, some sort of genetic material and cytoplasm.
Recorded observations of Mercury date back to at least the first millennium BC. There are no definite answers on who "discovered" it.

It is most likely that paranormal beliefs occurred first since they are founded on unexplained experiences. Without considering their reality, these early observations and experiences most likely were first. Religion likely sprung at least in part from man's attempts to understand and rationalize these observations and experiences. Science arose as reliable observations of the physical world took over from religious beliefs and superstitions.

The formation of a solid product from reaction of at least two components of a fluid phase. The final fluid phase in which reaction occurs is usually obtained by mixing at least two distinct fluid phases each of which is missing at least one of the necessary components of reaction but which together contain all the required components for the reaction.

A scientist may create an hypothesis on the basis of their observations. If their observations are carelessly made or recorded then any hypotheses they offer will be inaccurate reflections of nature. A scientist may alternatively collect observations to test an hypothesis. If these observations are carelessly made or recorded then the conclusions that the scientist makes about the hypothesis could very well be incorrect. At the very least the conclusions they draw would not be based on sound evidence (because the observations are unsound).
