Is there a logically valid way to call evolution science and creationism a pseudo-science?
I’m not sure what’s meant by “logically valid” here. Formal logic does have a notion of validity, but it’s not particularly useful for these kinds of questions. If I just came up with a definition for science and said that evolution matches that definition, thus therefore evolution is a science, it would be a logically valid argument… even if my argument made no sense.
For instance, if I said that “scientific fields are those which involve eating cheese on the moon, evolution involves eating cheese on the moon, thus evolution is a scientific field”, then technically, this is a logically valid argument. (See the link for an explanation of why.) It also makes no sense, but making sense is not a requirement for the technical meaning of “logical validity”.
So either the page has its own definition for what “logically valid” means, or it’s just making a meaningless but impressive-sounding claim.
