You posted:And Jesus answered them, “Have you not read in the Scriptures that God created them from the beginning and made them male and female.” (Matthew 19:4, Mark 10:6)
Jesus didn’t believe in evolution or the Big Bang and neither do Christians.

I don’t know that the scripture you cite contradicts evolution or the Big Bang theory. I believe God created the universe and everything in it. Just how He did it remains something of a mystery. Neither evolution nor the Big Bang theory contradict God’s existence nor His power, in my view.
As for the literal nature of the Genesis story, creation certainly could have occurred as Genesis describes, but even if the mechanism was different, Genesis is still TRUE. Many stylized or even fictional accounts contain great truths. For example, there was no such person as Tom Sawyer, but the story of the whitewashing of the fence (getting his friends to pay him for a job that he despised by acting as if it were fun) describes a truth that no one denies. Genesis stands for the truth that the creation of the universe and all that is in it was accomplished by God through His infinite power.
I’ll add this to my list of questions to ask in Heaven, if I ever get an audience with the Holy One.
And what is the dust we are created from? My guess we'd call that dust "Atomic particles", neutrons, electrons, protons, etc.
Science is just a language we are developing to describe, and write down the recipes for, God's creation.
Both scientists and theologians will end up at the same place with the same answer, they just take a different paths to get there.
