What’s your problem? It could mean something. It could not. God works however He wants. At one point He showed Constantine a similar sign.
She's right -- even if you establish that it's a sign,
who's to properly interpret that sign?The Pharao had dreams which were apparently from God, but it took Joseph to properly interpret the dreams.
A cross in the sky could mean anything. It could be a sign that the Chastisement is upon us -- Biden will win, followed by full Communism, being conquered by the Chinese, etc.
That interpretation is *just as likely*, if not MORE valid, than the interpretation that "Trump will take AZ".
Private interpretation of a sign seems to be about as fallible as trying to interpret Scripture with no guidance from the Church.
