The concept you mentioned, the "merged-timeline creation-evolution theory," does not correspond to any widely recognized or scientifically supported theory within the scientific community. It appears to be a speculative idea that attempts to reconcile certain aspects of biblical creation and the theory of evolution by proposing the existence of multiple timelines or dimensions.
In scientific discussions, the theory of evolution refers to the well-established scientific understanding of how life on Earth has changed over time through natural selection and genetic variation. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, and comparative anatomy. Evolution does not rely on the existence of additional dimensions beyond the four dimensions of space and time that we experience.
On the other hand, biblical creation refers to the religious belief that the universe and all living beings were created by a divine entity as described in religious texts. Creation stories can vary among different religious traditions.
While some individuals may attempt to reconcile their religious beliefs with scientific concepts, such as evolution, by proposing speculative ideas like merged timelines or extra dimensions, it is important to note that these ideas fall outside the scope of scientific investigation. Science is concerned with empirical evidence, testable hypotheses, and peer-reviewed research, while matters of faith and religious beliefs often rely on philosophical, spiritual, or theological considerations.
It's worth mentioning that interpretations of religious texts can vary among different religious communities, and individuals may hold diverse perspectives on the relationship between their faith and scientific theories.
