Only if you take a very broad view. Modern Christianity can probably be traced from the Council of Nicaea (from which the Nicene Creed takes its name) in 325 AD.
However (a) this was a meeting of existing Christian bishops, so could not really be said to be "creating" anything new, and (b) Niceae is in modern day Turkey part of what would later by the Byzantine empire - only by some stretch could you call it Roman (although it was sometimes referred to as the Eastern Roman Empire, but only after 330 AD - 5 years after the Council met).
So the better answer is probably "no".
Modern Christianity probably split from other monotheistic beliefs shortly after the death of Christ. What separates Christians from other montheists is the belief in the divinity of Christ.
No. Christianity existed long before Constantine even existed. In fact we have historical records going back to the time of Christ of Christians. The Christians were persecuted by the Roman empire for 100s of years prior to the time of Constantine and we have records of many martyrs for the faith. Constantine was the first Roman empire to legalize Christianity in the entire Roman empire because of a vision he had seen of a cross on the hill that he believed was from the Christian God telling him he would be victorious in his battle against the competing Caesar.
Constantine himself was not baptized at least until on his death bed. So it is unclear how Christian he was during his life. But he did improve things for the Christians by making it legal to practice. Although he did not make paganism illegal he did eventually withdraw funding to pagan temples causing them eventually to go out of business. There was no need to force these closures as a lack of funding was enough.
Constantine played no role in the formation of The Bible canon. The canon had long been in the process of being made but it had many setbacks because the people who worked on it had to do so in secret because of persecution and many people were martyred so the process kept being delayed. It wasn't until the legalization of Christianity that bishops were free to travel about and they could finish the work of the bible canon which was finished by the early 5th century. It was not done at an official ecumenical council as some believe but done in Northern Africa.

No, Catholicism was founded by Jesus Christ and spread by his apostles. When Constantine the Great made the religion legal, however, it did give a tremendous boost to the Church since they no longer had to hide from authorities and could openly practice their faith.
No one knows when the first Christians came to England. Christianity had come to England before 314 a.d. So Christianity came there during the period the Roman Empire persecuted Christianity.
Of course they did not. Jesus was a person. You do not invent a person. Moreover, Jesus was a Jew, not a Roman.
No, the Romans did not invent bowls. Bowls were around for thousands of years before the Romans existd.
No. People other than the Romans had teeth.
No one. The Romans weren't looking for Jesus. The Israeli religious leaders arrested Jesus, took Him to the Romans, handed Him over to them, and demanded that they (Romans) execute Him.
No, the Romans did not invent bricks, but they did invent concrete.
