Migrating: Natural Propensity of Humans ( and Birds)!

     How did all the continents become populated with members of the human species?  Obviously, human beings love to travel!  Sometimes, as is presently the case with migrating Syrians and Africans, it's out of fear of being killed, but many times it stems from a thirst for adventure or for searching for a land flowing with milk and honey--as in the story of the Jews' plight from Egypt. 
     Migrants don't always get a warm welcome in the lands they journey to.  Witness how many Americans yell to the Hispanic migrants entering the US, "Go home where you belong!"  But occasionally, migrants receive a warm welcome--as in the case when the German Chancellor, Angela Merkel, recently encouraged fleeing Syrians, "Come to Germany!"  The issue of whether the migrants enter legally or illegally is a matter of how the country to which they go regards them, e.g., the legal status bestowed on them, not how they feel about themselves and what within is driving them forth.
     Note that birds are simply tolerated by the countries they fly over and nest.  Nevertheless, occasionally, even birds are shooed away as being pests!
     In the instances of humans on a migration track, countries may find reason to welcome them.  Youthful Hispanics on the prowl in the US are tolerated by those governmental officials who see the migrants as potential workers, capable of helping to pay for aged citizenry in their retirement years.  Moreover, US business finds Hispanics non-complaining, industrious workers and family-oriented, willing to work for what wages are offered them, making fewer demands on corporate management.
     Regardless how receptive any particular people or government may be, migrants are on a self-propelling mission to go wherever their inner Spirit moves them!  They have so acted in accord with their nature as human beings; and they will so act in millennia to come!
