What you say so far is very interesting to me. How do I become a Buddhist. 

Once there was a man called Upali. He was the follower of another religion and he went to the Buddha in order to argue with him and try to convert him. But after talking to the Buddha, he was so impressed that he decided to become a follower of the Buddha. But the Buddha said:

"Make a proper investigation first. Proper investigation is good for a well-known person like yourself."

"Now I am even more pleased and satisfied when the Lord says to me: 'Make a proper investigation first.' For if members of another religion had secured me as a discipline they would have paraded a banner all around the town saying: 'Upali has joined our religion.' But the Lord says to me: Make a proper investigation first. Proper investigation is good for a well-known person like yourself."

In Buddhism, understanding is the most important thing and understanding takes time. So do not impulsively rush into Buddhism. Take your time, ask questions, consider carefully, and then make your decision. The Buddha was not interested in having a large number of disciples. He was concerned that people should follow his teachings as a result of a careful investigation and consideration of the facts.
