So how would you expect science to falsify a miracle?
By laboratory experiment, scientists cannot falsify an alternative explanation for what is observed in the paleontologist's dig.
If a person believes God created each kind specially, no laboratory experiment can falsify his belief.
Likewise if a person believes space aliens (panspermia) seeded each kind, no laboratory experiment can falsify his belief.
The principles of the lab and the dig are set in contrast to each other. In the lab, the absence of evidence is evidence of absence. In the dig, the absence of evidence is not evidence of absence.
The one cannot not be superimposed on the other, i.e. lab to dig is a belief as surely as Creation and Panspermia.
Precious few creatures that ever lived left a complete record of themselves, i.e. fossils much less DNA much less a historical record.
At the root, the "tree of life" is and will always be a theoretical continuum which people are free to accept or reject.
