I am questioning everything that is happening in my life

from birth, we are supposed to follow some religion or follow some tradition and no one ever told us why, when a child questions their belief, they think that this child is not obedient.

now when I gave up on god, became nastic; now I am questioning everything and sometimes I feel like my whole life is a lie. I live where people dragging me. & I believe that everyone is nice and nobody is here to harm anyone. there is a god somewhere and balancing everyone's karma. 

now I feel like there is no god, no karma theory, no religious drama. people are dumb, if tomorrow someone came up with another god drama, they will believe in it. if you live on this stupid earth, it's hard to live without having faith in one or another god.

I have many questions, such as

1. why we are here and not somewhere else?
2. why is something happening in this world? how is that's related to humans and god?
3. who is the god? what is god? what he will do? where do they stay?
4. what is faith? who came up with faith?
5. what is love? what is happiness? what is consciousness? what is the definition?
6. why there is a marriage institution? why there is family?
7. why did people lose their interest in this stupid society and be monks?
8. why death is not in our hands?
9. is there any afterlife? where is this after land?
