The Massachusetts Bay Colony was founded by the Puritans, a religious minority group who migrated to the New World seeking to create a model religious community. They were a group of English Protestants of the late 16th and 17th centuries who regarded the Reformation of the Church of England under Elizabeth as incomplete and sought to simplify and regulate forms of worship.
We can only theorize about how the life would be if the humans appeared earlier on the Earth, as we can not create a perfect and accurate picture of how would the things have been.
If the humans were developing in the same manner as we had, than we can say that the humans would have been much more advanced. The technology would have much better, probably missions to the other planets would have been regular. The population would probably be higher, with most of the population being concentrated in highly advanced megalopolises.
The environment though would probably be in a terrible condition, with enormous loss in biodiversity across the globe, decline in the forests, and much emptier (with life) oceans. On the other hand, there's every chance that with the more advanced technology multiple animals and plants would have been resurrected, even some extinct very long time ago.
