I hear this a lot and I could see why people think that. Some of the practices and wisdom overlap.: (stillness, humility, kindness, detachment from possessions, etc)

But Christianity’s cosmology and call on a person’s life is not inwardly focused (where there is more overlap with Buddhism).

The call is to bring heaven to earth: to speak truth, to oppose evil, to fix poverty, to heal the sick, to bring people hope they lost a long time ago, to teach people about the God made human in Jesus who did the work to make it all possible.

I believe there is goodness is Buddhism but I don’t think Jesus and Buddha would have haven’t along philosophically on what mattered most to each of them.
