At first sight, it is a fact of speaking to communicate between us, and it is the most complicated thing we need to learn how to do correctly.
We learn to speak at a young age, from two years old, and this language develops throughout our lives. The fact of speaking allows us to express our needs, our feelings, our desires, our fears, our happiness, our love, and our devotion.
The list is very long, but it is what makes us the most human, and we must, in principle, know how to communicate well and speak between ourselves to express what we have inside so that our interlocutor can understand us well.
Another thing that makes us human is the fact of helping each other. We, humans, must support others in the most challenging moments of their lives, helping them when they ask or without them asking in case of war or natural phenomena.
To help others is to be there for them, share with them, and empathize with them. That is what keeps this humanity in us, which is essential for our survival and for humans on this planet.
Does love make us human? Apparently, yes, because without love, we cannot live.
If a mother doesn't love her baby, how can she care for him? Without love, how can we be creative, inventors, and artists? We must love what we do to do it well.
Without love, we will not be able to evolve as much as humans. The fact of loving gives us the strength to continue in any field. To love allows us to advance, to exist.
We all are human, but to be an excellent human on this earth is what we all don't know how to be.
