Is Paul’s appeal in 1 Cor 15:3-8 based a call for blind faith or a demonstration of evidence? So what?

1 Cor 15:3-7 For I handed down to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He was raised on the third day according to the Scriptures, 5 and that He appeared to Cephas, then to the twelve. 6 After that He appeared to more than five hundred brothers and sisters at one time, most of whom remain until now, but some have fallen asleep; 7 then He appeared to James, then to all the apostles; 8 and last of all, as to one untimely born, He appeared to me also.
