First of all, medyo layu ra kau ang comparison bro.
An ant is limited and without a capability to learn and understand, whereas man can learn and understand though limited but can manage to understand. That's why Jesus is fond on using parables to simplify things and to explain things to his disciples and the people.
Man can understand, not just all at once and definitely not all especially things we are not "yet" capable of.
For following ways, ants dont follow a man unless he can speak ant language (or become antman

)
Man can follow God's teachigs and ways, it is in his stubborness and hard headed that man tends to not obey and follow God's way.
