No. That is the SECOND STEP.

hypotheses
Condensation indicates formation of clouds. It is the 2nd step of water cycle.
The Big Bang is the theory that was developed to describe the origins of the universe.
...The soil
the impact theory.
the theory of plate tectonics
The first step in a scientific investigation would be the formation of a hypothesis.
Formation of a zygote
Have a theory which you think is viable.
filtration
The first step is weathering.
Weathering
The first step is Peat, The second step is lignite, The third step is Bitimunous, and the fourth step is Anthracrite and Their is no Fifth step.
A hypothesis is the first step to elaborate a theory; it is not a true explanation.
The first stage in coal formation is the deposition of material composed of twigs, leaves, branches, and other plant debris..
Deposition is the first step in the formation of new sedimentary.
The big bang theory has nothing to do with the formation of life.
A theory of the origin and formation of the universe (the cosmos).
