Let's analyze some of these similarities - Similarities between Krishna's father Vasudev and Christ's father Joseph - Joseph had eleven brothers (in Matthew's genealogy), meaning they were all 12 brothers.The name "Vasudev" is actually a part of the famous Hindu "12 syllable mantra".
Surprisingly, Jesus Christ has a very similar story as well in which the evil king Herod actually issued a royal decree to warrant Christ's death.
But why were early Christian scholars trying to introduce this number? The only answer that prominent experts would agree on is that it originated in Hinduism.
Now I ask any Chritian skeptics, do you still disagree?
Both Christ and Krishna clearly state that the only way to salvation is through them - Lord Krishna, in Bhagwat Geeta, states that Moksha is attained by those who completely surrender to Him and Him alone.
Those who do not surrender to Lord Krishna and rather worship false gods will not attain Moksha/Salvation/Nirvana.
