for human survival, more focus should be on expanding into space

Besides needing to pack every bit of supplies, with the exception of growing some plants, the effects of zero or lesser gravity on Earth organisms has proven to be troublesome. If the transportation to this outside-the-solar-system took the same amount of time or more there would be several effects on these zero gravity babies. They would have weaker muscles because of the lack of gravity to name two balance would be nonexistent when returning to a gravitational environment. Currently astronauts experience muscule loss in outer space even though they have developed methods to work out. Besides several physical issues with long term zero or low gravity environment exposure there are several mental issues as well.
The mental stress that would be involved with those who journey to the colonized location would have to be willing to leave absolutely everything they know behind. Along with that , isolation issues would be incredibly difficult to overcome. Knowing that you could never see anyone you know not selected for the trip to the colony would weigh heavily on day-to-day life possibly causing people to not focus entirely on the task at hand. With several personal mental issues to deal with social issues would be exacerbated by being in space.
If interpersonal issues arise, having people in close quarters to each other could be problematic. Even if people remain professional, it can be very difficult to overcome personality conflicts especially in close proximity all the time. Additionally, if someone is not performing their duties up to standards, there would be limited ways to counsel them or replace if need be.
With the state of modern space technology, the funding of the colonization of outer space, let alone other solar systems is impractical. The likelihood of catastrophic events is much higher when traveling through space and attempting to colonize an unknown location or planet. Yes there is possibility of an extinction event, but the danger of an asteroid, the sun exploding or natural disasters is a fraction of that of space colonization.
As stated above, Voyager I took nearly 40 years to reach the edge of the solar system, not even to a location that we could inhabit. The issues of prolonged zero gravity environment exposure have still not been overcome and studies of rats born in space have shown the negative effects that go along with being born in zero gravity environments then returning to a higher gravitational environment.
The mental issues that would go along with leaving Earth to form a colony elsewhere in or out of the solar system are a big deal. They go beyond keeping busy. If you look at any refugee situation where people have to leave their homes, belongings, and often times loved ones there is incredible amounts of stress and hardship that come along with that. Yes people would make the choice to participate in the colonization, but that would not take away from the stress of leaving absolutely everything and everyone not participating in the colonization behind.
Not only would the same extinction possibilities apply to Mars and outside the solar system colonies, but the dangers, logistics, and funding involved with mass human travel in space are incredibly high and would not protect the human race from possible extinction events.
