You still did not address the texts I quoted here is something for your consideration.
Wuest Word Studies – K. S. Wuest*– Vincent (Word Studies In The New Testament – M. R. Vincent) says, “It is important that the preliminary definition be clearly understood, since the following examples illustrate it.* The key is furnished by verse 27 , as seeing him who is invisible. Faith apprehends as a real fact what is not revealed to the senses. It rests on that fact, acts upon it, and is upheld by it in the face of all that seems to contradict it. Faith is real seeing.” The word “substance” deserves careful treatment. It is hupostasis, made up of stasis “to stand,” and hupo “under,” thus “that which stands under, a foundation.” Thus, it speaks of the ground on which one builds a hope.
Here is an original context where the word is used
by H. R. Minn, the story of a woman named Dionysia. She is described as “a woman of set jaw and grim determination.” *It seems that she had lost a case in a local court over a piece of land to which she laid claim. *Not satisfied with the decision of a lower court, she determined to take her case to a higher court in Alexandria. *She sent her slave to that city, with the legal documents safely encased in a stone box. *On the way, the slave lost his life in a fire, which destroyed the inn where he had put up for the night. *For 2,000 years, the sands of the desert covered the ruins of the inn, the charred bones of the slave, and the stone box.
Archaeologists have recently uncovered these remains. *In the box, they found the legal documents. *They read the note, which this woman had sent to the judge in Alexandria, “In order that my lord the judge may know that my appeal is just, I attach my hupostasis.” *That which was attached to this note, she designated by the Greek word translated “substance” in Heb. 11:1. *The attached document was translated and found to be the title-deed to the piece of land, which she claimed as her own possession, the evidence of her ownership.
So faith is the substance of things hoped for = evidence
