No. That is the SECOND STEP.
In the Scientific Method, the first step is to ask a question or make an observation. The problem / question / observation is the subject of the investigation. Once the question exists, a theory (hypothesis, conjecture) can be made, which can be proven or disproven through experimentation.
The Big Bang is the theory that was developed to describe the origins of the universe.
The first step in the dissolving process is when the solute particles come into contact with the solvent. This interaction allows the solute particles to break apart and disperse in the solvent, leading to the formation of a homogeneous solution.
charles darwin prposed the 1st theory to explain the formation of life on the earth
the theory of plate tectonics
The Nebula Theory is also known as the Solar Nebula Theory. It is a widely accepted model for the formation of our solar system.
The first step in a scientific investigation would be the formation of a hypothesis.
Have a theory which you think is viable.
Formation of a zygote
filtration
The first step is weathering.
A hypothesis is the first step to elaborate a theory; it is not a true explanation.
Weathering
The big bang theory has nothing to do with the formation of life.
That's the first step.
The first step of coal formation is the accumulation of plant material in a swampy environment. As plants die, they accumulate in layers and start to decay. Over time, the plant material undergoes chemical and physical changes, eventually transforming into peat.
the nebular theory
A theory of the origin and formation of the universe (the cosmos).
