My guess is that the author of that question wrongly believes that the conception of Jesus Christ was The Immaculate Conception, after all this would be some action which you could see, and of which you might be able to take a video. The fact is that the Immaculate Conception was not the conception of Jesus Christ; nor was it an action of any sort. Do you know what truly was, according to Christianity, the Immaculate Conception? Don't look it up anywhere, just answer yes or no as to whether or not you know for sure. If I get a few answers either way, I'll tell you just what was it. And, yes I know the meaning of the Immaculate Conception even though I do not practice any faith; after all I used to be a practicing Catholic. Hint: it reportedly was revealed to Bernadette at Lourdes.
All the best,
