Then why is the globe the first thing a child sees in the classroom
Are you kidding?
Why do teachers put the alphabet up on the wall?
Why do they have books so that children can learn to read?
Why have a clock so that children can learn the time?
why teach kids about Columbus & Newton ?
I doubt that 3-4 year olds learn about Columbus and Newton.
If this isn't indoctrination I don't know what is.
I don't think you know what indoctrination is.
Indoctrination involves not allowing people to think for themselves. Cults do it. They teach their leader's interpretation of the Bible and questioning is not allowed. Their group, alone, has the truth and if you question, you are doubting God.
I have read testimonies from former cult members who said that they were invited for a meal, or a weekend away with the group, were watched at all times in case they tried to read other literature, phone someone or #even have 5 minutes to think about all the stuff that they had heard. They had very little sleep so that they couldn't think straight and were more susceptible to what they were being taught. If they expressed a desire to leave the group, they were told that a) they were being ungrateful after all that people had done for them and b) the devil was trying to tempt them because he knew that the group had the truth. Anyone who was strong enough to stand out against all that and leave was told they were going to hell. Anyone who stayed was given more and more of the group's teaching. No literature was allowed, unless it had been written by the founder of the cult. People were gradually cut off from family and friends, "they don't understand or want the best for you". The new recruit would be sent out to knock on doors, sell books and make money for the cult. Eventually, they had no other form of support except the group, and probably had a genuine belief that if they left they would die and go straight to hell.
THAT is indoctrination.
Do you have any evidence that if a child asks their teacher why the world is a globe, they are told to "sit down, shut up and not ask questions"?
Do you have any evidence that science teachers say, "this is the shape of the earth - no, you can't study, do any experiments or ask questions; you might prove me to be wrong"?
If a parent was trying to indoctrinate a child I doubt they would let them go to school at all, or mix with others, They would be home-schooled and allowed to think only what the parents thought.
In my limited experience with children, they ask questions all the time. They are inquisitive; they want to know things. Sometimes adults are forced to study/take short courses so they can keep up with their kids favourite subjects. This may be doubly so if the child is extra bright.
Having a globe in a classroom is a million miles from indoctrination.
And another thing when ever I'm watching a TV show or a film, there it is lurking in the corner, what is it, a globe. They never fail to show one.
You've been watching the wrong programmes.
