Because the greater the number of organisms that they test, the more certain they can be of a data. :)
Scientists use many individuals in experiments to ensure that their results are statistically reliable and to account for biological variability among subjects. A larger sample size allows researchers to detect patterns and effects more accurately, reducing the likelihood of random chance influencing the results. Additionally, using multiple individuals helps in generalizing findings to a broader population, enhancing the validity and applicability of the conclusions drawn from the study.
In an experiment that involves many people or animals, it is important to test many individuals to avoid experimental error. If only one individual were to be tested in the experiment, it would be difficult to say whether the results were a product of the test, or if it was just a result that the particular individual produced. By testing many, scientists can say definitively that their hypothesis was correct or incorrect because a wide variety of test subjects responded in the same way.

They go to school for degrees in areas such as biology, physics, engineering, and geology. You can then try finding a job at a research facility, many science colleges have these on campus.
No, historically many scientists have been strongly religious; nowadays more scientists tend to be atheists than the general public and it also seems likely that the more senior the scientist, the more likely they are to be atheist. There are scientists who are religious and try to contort science to prove their religious beliefs. On the other hand, there are scientists who are religious and understand perfectly that religion and science are completely separate and distinct. In the world of science, those within it are all unique individuals, just like the rest of the world. So one way of believing or thinking anything can't be assumed.
Scientists use many individuals in their experiments to ensure that their results are statistically valid and reliable. A larger sample size helps account for variability and reduces the impact of outliers, allowing for more accurate conclusions. Additionally, using multiple subjects increases the likelihood that the findings can be generalized to a broader population. This approach enhances the robustness of the research and strengthens the overall validity of the study.

Scientists examine all of the data and try to see what conclusion will fit all of them.
By testing them.
Scientists try to identify as many relevant variables as possible in order to understand the complexity of natural phenomena and to make accurate predictions about how various factors interact with one another. By considering a wide range of variables, scientists can better account for potential influences on the outcomes of their experiments and studies. This comprehensive approach leads to more robust and reliable conclusions.
