You eny the existence of God because you think the universe can come out of nothingness, and at the same time deny afterlife because you think that nothing can come out of nothingness.

I don't believe in God because there's no proof God exists, of course there's no proof he/she/it doesn't exist either, just like there's no proof for or against the existence of the devil but I prefer to just trust into facts and my logic and rely on science here. I do believe in the afterlife though, in a spiritual way, I just don't believe heaven or hell exist. I sometimes even doubt the afterlife but then I think the thought of something after death kinda takes away my fear a little.4

For the first part it's very simple.
First, believe in God and the origin of the universe are two different things. They are not mutually exclusive. It doesn't have to be this or that. It can be both. Neither excludes the other.
Second, disbelieve in God does not require an alternate explanation. If an alternate explanation is available, fine, but it's not required.
If I go in my front yard and find a piece of paper I might think, "Hmmm, I wonder where this came from?". If I don't know, it does not automatically mean that God put it there.
I might also think "It's common for wind to blow paper around, maybe that's how it got there." We know from experience that this can happen. We even know a scientifically sound reason how it happens. Just because I can't prove the wind blew it there does not mean God put it there.
Whether I have an alternate explanation or not, I can't conclude that God put it there.
For the second part of the question. It's similar to the first. Believe in God and believe in an afterlife are two different things. Neither belief nor disbelief in either one excludes the other.
To put the two parts together, you are comparing apples and oranges. The origins of the universe and an afterlife are two very different things. They each need to stand on their own. Once again, these two things are not mutually exclusive. They can both exist, they can both not exist, or only one can exist. There is no contradiction there because neither depends on the other.0
