If you read my earlier comment, you'll notice I cited Cook 2017 and Ware 2014, both of which argue that the creed implies an empty tomb. You might disagree with their view, but it isn't something I came up with, nor did I ever claim that the mention was explicit.
I'd also cite Dale Allison's recent book on the resurrection, where he comes to the conclusion that "Jesus was probably laid in a tomb which some women later found empty, and Christian imagination turned their report into a dramatic story that grew in the telling" (p. 163). The historicity of the empty tomb isn't just something apologists throw out there for a laugh.
