You don't need an explanation for everything. Recognize that there are such things as miracles, events for which there are no explanations. Later, knowledge may explain those events quite easily.
The fact that you can plant a seed and it becomes a flower, share a bit of knowledge and it becomes another's, smile at someone and receive a smile in return are common miracles.
Your duty to yourself is to believe that for which you have sufficient evidence, and to suspend your judgment when you have not. Any sufficiently advanced technology is indistinguishable from magic.
Some things have to be believed to be seen. Vision is the art of seeing invisible things.
