All cells come from preexisting cells
Christopher Columbus was initially trying to prove that it was possible to reach Asia by sailing westward across the Atlantic Ocean. He believed that he could find a shorter trade route to Asia, bypassing the established overland routes that were controlled by the Ottomans.
Science begins with theory.In other words, science is the process of trying to answer questions by formulating likely explanations, called "theories", and then designing experiments that will either disprove or prove that the theory is true.
Albert Einstein, who is not quite current but who is at least relatively recent, did actually revise Isaac Newton's original theory of gravity, and even now, many other theoretical physicists are trying to improve on Einstein. As for Newton's laws of mechanics (force equals mass times acceleration, and so forth) nobody is trying to improve on those. As far as we can tell, Newton got that exactly right.
In science, if you are trying to "prove" a theory (that's confirm it or falsify it), you must use experimental evidence. That is, you use the theory to make a prediction and then try it out. It's no good just to sit around and talk about it.
how can you prove that earth is a sphere by looking at the pole st

Cell theory
Rudolf Virchow was trying to advance the concept that diseases have cellular origin and proposed the idea that cells arise from pre-existing cells (omnis cellula e cellula). He aimed to show that diseases are caused by changes within cells themselves, rather than being caused by external factors. Virchow's work laid the foundation for modern cellular pathology and our understanding of the cellular basis of disease.
The theory of spontaneous generation was false.
Spontaneous generation does not happen.
It is what you are trying to prove
You start by speaking proper English. 'How do you prove you WERE'NT trying to break into someone's webmail?'
used to prove the analogous homologous characteristics of evolution
nothing
what are you trying to prove? if you were trying to prove a lemon can make lemonade the lemon can be used as a product to ensure that the theory is in fact "feasible"
