The climates and atmospheres of Venus, Mars, Mercury, etc...

So I’ve entered my senior year of high school, and as an elective I decided to choose Astronomy & Geology. So far, I find the astronomy to be very gripping and interesting. Every time I walk in there though, I’m reminded of Destiny haha. That brings me to my question... In learning about the inner planets and the solar system, I’ve noticed a lot of inaccuracies. I feel like there’s probably a lot of plot armor going on, but I don’t know what the real answers are. So my question is, how in the hell did the Traveler manage to like... make these planets livable? Mars is more easily understandable, and it’s actually something NASA is interested in so it’s not too radical of an idea. However, what about Venus and Mercury? Venus’ atmosphere is so thick and heavy you can’t see into the planet, and if you managed to get on the surface, you’d be crushed. The winds move faster than the rotation of the planet, and basically everything is volcanoes. In Destiny, you can see out into mountains in the Ishtar Sink and there’s even grass and trees. There’s geothermal pools. And on Mercury, the confusion should be pretty obvious hereβ€” how do you make a β€œGarden World” out of a planet with hardly any atmosphere and is tidally-locked with the Sun? Not to mention right next to it. So what I want to know is, what exactly is the extent of the Traveler’s power? Is there any lore on as to how it does this, and why? The fact it’s able to make situations like those livable is curious. Maybe I’m just thinking too much into it but I’d appreciate any ideas you have or any information that’s out there.

TL;DR: space magic. answered!

Unless we find a way to make Mars' gravity stonger, any humans born there would never be able to visit earth due to the higher pressures of our atmosphere

Less gravity means bones wouldn't have to develop as much to hold your weight, so any trips to earth wouldn't be enjoyable due to the excruciating pain

In order to terraform mars we need enough greenhouse gasses to make an atmosphere... let’s take all the excess gasses from earth and put them on mars solving global warming and colonising mars in one fell swoop.

There is definitely nothing wrong with this plan...
