Is it possible, that if you trace back to when the first human was set on earth, then in some way, every person on the planet is related?

I guess it is technically possible. But of course one of the earlier species displaying humanistic traits is the Australopithecus Afarensis. This species was confirmed to have walked upright because of evidence portrayed by the pelvis bone. Also, the creatures were fully developed around the age of 12. This was shown in the Wisdom teeth. The first member of this species found was named "Lucy".

BTW I love all the questions you post! :-)

whose power in the senate is equal to the power of the speaker of the house?

according to romans 13: 1-7, 1st peter 2: 12-14, and 1 timothy 2: 1-4, christians as citizens have specific responsibilities to a nation that gives liberties to its people. christians are obliged to live as good citizens by submitting to the human government. honor, or respect, is due to men in the high governmental station. a christian should reflect such respect not to gain some favor but because it is god’s will. peter 2: 14 notes that the purpose of the human government is to promote peace and justice in society. to submit to human government, peter includes three elements; obedience, respect, and good deeds.
