In your opinion what causes christians to believe in Jesus

Advertising is 60% pseudoscience, 40% copying what the next guy is doing.

Yet from a coercion standpoint, it’s phenomenally effective. The effectiveness of advertising demonstrates, once again, that you don’t know what the ever-loving fuck you’re talking about.

One of the most efficacious tactics in advertising is to appeal to the emotions of your target audience. though in the case of religious indoctrination there are longstanding trends of getting people as young as possible, as others have pointed out, it is hard to resist propaganda and indoctrination when you have no idea what it is, as a small child would not, of course. 

There is also outright chicanery of course, I mean people don't travel to Lourdes because they think miracles are irrational hokum, yet they are. 

Though adults can be very suggestible as well of course, and again appealing to the emotional needs of a target is very effective and powerful way to indoctrinate them. It isn't only religions that have utilised this of course.
