Of course it's plausible. However, that does not mean it is proven. In fact, as is any matter of faith, it can neither be proven nor disproved scientifically. There are a number of ways in which G-d could have created the universe per the biblical creation story and have everything we measure come out as it does. The following are two examples:

1. G-d created the world about 6000 years ago, but part of creation was to put dinosaur bones in the rocks, oil underground, the stars and galaxies as they would need to be to seem the way they do now.

2. G-d created the universe in 6 days as measured by the clock when the universe was a fraction of a second old, and then when it was a bit older, etc. As the universe expanded, the subjective time measurement resulting from that slowed down, so that a day as measured at creation would today seem to us to be ~8 billion years. Another day after that ~4 billion years more, etc. such that 6 days end up seeming like about 14 billion years when measured today.

These two examples show that it is plausible, in the sense that nothing we measure contradicts creation as the explanation for how the universe came to be.
