Could Earth be populated with dinosaurs today? Do any dinosaur-like worlds still exist in the Milky Way or has their time truly passed even on a galactic scale?

Dinosaurs could exist on the Earth today if they were reintroduced, but this would not be compatible with human life so will not be done by Creator. There are other worlds within the Milky Way Galaxy undergoing similar repair and transformation using similar strategies because they have been laid waste by the extraterrestrials in their manipulation and savagery, having spread throughout the galaxy to inventory and catalogue other worlds and then preying on them to exploit whatever they chose for their own benefit. Keep in mind all of the extraterrestrial species who belong to the Dark Extraterrestrial Alliance are savage in their makeup and functional sociopaths devoid of conscience and unable to have any feelings of love or compassion. They will destroy other life forms with impunity and may do so simply for the perverse pleasure in exercising power over them. This is a depraved way of thinking and an extreme state of depravity because they have been lowered to be on a par with the demonic fallen angels and are in grave danger of being disconnected from life support as well. At this point, only the divine human can save them—it is up to you to make healing requests on their behalf to overcome all of the negativity that has befallen them and they are trapped within.
