Science” is perverting what the Holy Bible Teaches on this subject, to justify the SINFUL lives of those who CHOOSE to be homosexual, which is clearly against what God says.
You are spot on by saying it is impossible for homosexuals to be born that way.
We are born in sin. Sin has been past down from Adam, (the original sin) which corrupts our nature. So we have this proclivity for sin, a sinful nature, to rebel against God, against His Law and go our own way.
My 2 year old granddaughter at does just that. She is in the terrible two stage. She knows nothing about sex though. Newborns know nothing about anything. They come out crying, probably cold and look at Mommy. It is that miracle moment for us. God created male and female. You are either one or the other, that is simple science, observing a biological sex organ. The doctor or whoever delivered the baby exclaims _ by simple observation, " It's a boy" or "It's a girl".
Now at that moment, the desires of a baby are few: warmth, comfort, personal contact with Mommy, food. He or she has few desires. They desire/need to feel security. If they they are hungry they cry, if they are wet, they cry, if they are uncomfortable, in pain or sick, they cry. They have no sexual desires beyond intil they start exploring the world. They see something and want to touch it, examine it and usually put it in their mouths.
Good Science is not incorrect. Distorted assumptions snd theories are not good science. A gene that cause you to behave or desire? Sounds like a stretch of someone's imagination desperately bent on finding evidence to disprove the Bible in some way. The motive behind the Hubble Telescope was to find evidence that disproves the existence of God. Science becomes maligned and corrupted when it goes off on a tangent like this.
Behavior begins on day one. A newborn baby learns how to get what they want. It doesn't take long. They discover quickly that when the cry, theu get your attention. So they learn to put on this phony crying routine to get their way. They manipulate, disobey and practice sinning before they can talk. Then they just continue to express themselves sinfully - not all the time of course. They are little angels too
It's a selfish endeavor about getting what they want.
Anger is a response of someone who feels deprived, not getting what they want, instant gratification. And that is what we see in infants who are little sinners who grow up to be big sinners. But at birth, desires are born, behavior is also born. We learn quickly what we need and want. They desire for Mommy, comfort, the mother's breast and these may be the only inborn desires and needs. Then as they grow they want more. As far as I know, there is no sexual desire at least until hormones kick in at puberty. And until someone tells them or they see photos or videos, they have no knowledge or understanding of sex. They know they are different when they see a naked baby of the opposite sex, and they knowbthenopposite sex behaves differently too, but that's it. God made us different, with differeng abilities. Males are stroñger, women are more emotional. He gave us different purposes, roles to play - too lengthy to go into. We are certainly different in many ways. Our desires, needs, values and behavior is different. Desires, values and behavior develop over time. But most of us can agree that the desire for sex comes after puberty or even years later.
Finally, I would like to add, that medical science will tell you tha it is impossible to change a person's sex. Even with hormones and operations, the person's sex is written in the genetic code and functions down to the cellular level. So on the outside superficial changes and behavior or hormones injected are seen, but this is not ever a total transformation. THE PERSON IS STILL THE SEX THEY WERE BORN AND ANYTHING OTHER THAN THAT IS JUST A CHARADE. Homosexuality is like a performance in a play where you act out a part, put on a custom and pretend you are someone else.
The Bible clearly says all sins_ from birth on_ are by choice. Your first act of sex was someone's choice, if not consensual. The result is a feeling, a rush that is very enjoyable, something you want more of. And so that is when your sexual desire grows and IF it happens to be with the same sex, and it turns into a habitual thing, that is when one becomes a homosexual or at least a bi-sexual. They become confused at this time as to what their purpose in life is.
God's purpose is very clear. He made male and female to procreate and did not give us any options to choose from other than being a eunich.
