There are two forms of "theory." Colloquial usage associates the word with a "guess." However, the scientific usage of the word calls upon a body of evidence to explain scientific phenomenon. For instance, we know the universe is comprised of Atoms; Atomic theory explains the makeup through physics equations. Likewise, Evolution theory explains the mechanism that powers speciation, namely natural selection. Both Atomic and Evolutionary theory are supported by a large body of evidence.
Second answer
Evolution, the change in allele frequency over time in a population of organisms, is fact.
The theory of evolution by natural selection explains much about the fact of evolution.
That is what theories in science do. They explain phenomenon by being the result of many tested hypothesis, supported by myriad lines of converging evidence, be internally consistent and be able to generate prediction for further testing.

Natural selection occurs when four conditions are met:
1. There is variation among individuals.
2. That variation is at least partially heritable.
3. That variation is linked to differential reproductive success.
4. More individuals are born than can survive and reproduce.
The distribution of alleles changes due to random chance.
