Can comets create a microclimate crater on Mars 30km deep with 0.7bars?

[QUOTE="darkdave3000, post: 6839850, member: 610485"] [B]TL;DR Summary:[/B] Can comets either one or many create simultaneously overlapping impact craters for higher air pressures to breed algae and plant life as a micro climate? Is there a depth limit to crater creation on a planet? Let’s say Mars for a depth of 30km can it be done? Assuming the projectile is an icy comet. And we have the option to use more than one at whatever time interval. Also sequential and simultaneous clusters are an option too and we can give each rock angular momentum(spin). Scale height of Mars is 11.1km and according to my calculations from -7km elevation on Mars a -37km should yield 0.7bars. Since trees can survive on mountains with similar pressures and it’s within the Armstrong limit I am thinking a win win scenario if a planet killer was deflected from Earth and toward Mars as it will also carry water ice to the bottom of the new Martian crater as liquid water (it can stay liquid since there it’s below the Armstrong limit) for plant and algae life to breed if we so choose to plant them there. The water can also be rocket fuel and oxygen source after electrolysis in addition to drinking water. In this case soda since it will mix with CO2. A comet such as Haileys would have sufficient ice by it self to increase Martian atmospheric material, pressure and density by 1%. While negligible with just a single comet: with repeated engineered crashes up to a hundred we could double the Martian atmospheric density and pressures gradually reducing the required depth(by half from -30km to -15km ) of future micro climate semi habitable craters to terraform Martian atmosphere slowly with photosynthesis from CO2 to O2.
