Science has identified guiding principles in association with the formation of a snowflake. Symmetry is evidence of design. The atomic particles associated with a snowflake maintain consistency. All of these things are apprehended BY intelligence and they exhibit attributes that IMPLY intelligence. Otherwise we would not be able to distinguish a snowflake from a drop of rain.
If, from that point, one would derive the attribute of consciousness from the snowflake itself, he would be engaging in superstition. But it is not unreasonable to infer that many of the attributes of personhood are among those needed to design and build a snowflake.
