I would love to see credible evidence in support, to date I have not found any outside wishful thinking.

While it is evident that a number of Indian sages visited
Constantinople in Classical Antiquity, claims of significant influence in either direction have failed to gain wide acceptance.
Christianity revolves heavily around the life of
Jesus Christ as detailed in the Bible, whereas Hinduism is not based on any one personality or one book, but rather on the philosophy that there is god.
Buddhism, Hinduism and Christianity differ on fundamental beliefs on heaven, hell and reincarnation, to name a few.
So if we get into urreligion here and we look into possible connections, we see examples in the bible and other text showing trade routes were established between the two religions as far back as 1000BC. Despite picking this information out of mythology, to our best guess, it did take place in Israelite cultures. It shows no religious connection however. But the connection to Christianity cannot be substantiated in any way at this time. It shows 100% origin in Judaism.
Now if I wanted to build a connection, I would start to search in topics knowing and recognizing the true origin of Christianity lies in Hellenism plagiarizing Judaism. But as the religion evolved away from Judaism, it adopted many pagan practices native to Hellenism in this region over hundreds of years. The problem again when speaking of origins, is we see the religion adopting the Emperors divine status by plagiarizing the Imperal cult, which includes the "son of god" and speaking to large crowds, and many rhetorical similarities to guild authority and divinity to appeal to the emperors followers. They aimed this rhetorical prose at the gentiles in the Diaspora so that they would have a choice of worshipping the corrupt Emperor as "son of god" or the new "son of god" who sacrificed his life for the good of the people fighting a corrupt government.
Christianity surrounds the martyrdom of jesus in light of the divorce of Hellenistic Judaism from cultural judaism
