We can invent as many theories we like, and any one of them can be made to fit the facts. But that theory is always preferred which makes the fewest number of assumptions.
Interpretation
Theories should be simple and require minimal assumptions to explain facts.
In this quote, Albert Einstein emphasizes the importance of simplicity in scientific theories. He suggests that while it's possible to create numerous explanations for observed facts, the most valuable theory is the one that relies on the least assumptions, as it is more likely to be accurate and applicable.
In practice
During a scientific presentation to explain findings, you might use this quote to advocate for straightforward theories.
I cannot then believe in this concept of an anthropomorphic God who has the powers of interfering with these natural laws. As I said before, the most beautiful and most profound religious emotion that we can experience is the sensation of the mystical. And this mysticality is the power of all true science.

Knowing what your parents have gives you hints of things, but your genome is a totally unique combination of and interchange of DNA from your parents. There is no one else like you genetically.
Chance alone is at the source of every innovaton, of all creation in the biosphere. Pure chance, only chance, absolute but blind liberty is at the root of the prodigious edifice that is evolution... It today is the sole conceivable hypothesis, the only one that squares with observed and tested fact. Stating life began by the chance collision of particles of nucleic acid in the "prebiotic soup."
The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.
